Fullscreen SDL apps not using full width since 8.1 update

(I'm going to be cheeky and cut-and-paste this (with some edits) from an earlier post on the Gemini Planet Facebook page, so some people may recognise it if you spend time there.)
Since upgrading my Gemini from Android 7.1.1 to 8.1 I've hit a snag with the Amiga emulator UAE4ARM and other emulation apps that use the SDL library for handling video.
It looks as though the new OS may not be providing the correct screen width to whatever function the SDL libraries is using for their fullscreen display. Whether or not the Gemini's navigation bar is hidden, I lose 10% or so of the screen on the right hand side (or the left, if the navigation bar has been moved) when running these apps fullscreen.

"lightbox_close": "Close",
"lightbox_next": "Next",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
All of the apps I've seen this happen to are emulators (UAE4ARM, Vice64 and Unreal Speccy Portable) and while I'm not certain whether Unreal Speccy uses SDL the other two definitely do, which leads me to suspect it as the common factor. The DOS emulator Magic DOSbox uses a different display methodology and works perfectly in fullscreen landscape.
I've tried all available methods for hiding the navigation buttons; Gemini's new settings, UAE4ARM/SDL's built-in Immersive Mode and the Granular Immersive Mode app. All methods exhibit this truncated screen effect. It's interesting to note that in terms of raw pixels, the truncation appears at the same horizontal position that the navigation bar would appear if it were visible. This also coincides with the right side of the titlebar clock, and is only a few pixels to the right of where Planet's own App Bar cuts off, whether or not the navigation buttons are visible.
Everything points to the OS reporting the wrong screen width to certain apps and libraries when the navigation bar is hidden. None of these apps exhibited this behaviour under 7.1.1, but it's unclear to me whether this is a change in Android functionality or a result of something Planet have specifically tweaked for the Gemini firmware (perhaps related to the new built-in ability to hide the navigation buttons?)
I've tried the obvious Google searches but with fairly generic parameters such as "Oreo" "8.1" "width" "SDL" etc. I'm getting a lot of false positives and nothing of actual use.
Does anyone know what might be causing this, and whether there's a workaround to change whatever value the OS is reporting to SDL? I'm pretty sure I've exhausted all of the tweaks available under Developer Options but I don't mind using tools such as ADB to apply tweaks if necessary. I'm even prepared to root the Gemini if that's what's needed, although I'd rather avoid that if possible. I'm really hoping for the equivalent of an .ini or .plist file (you can tell I'm not an Android developer!) that I can tweak.
My next stop will be to contact Planet and let them know, in the perhaps vain hope that this is a simple bug/oversight that they can fix with a later update. The problem with Planet is that their e-mail based support system has no proper feedback channel, so you often don't even know whether your issue has been acknowledged let alone investigated. So I figured I'd run it past the folks in here first, in case I'm missing something obvious.
TIA for any assistance.

[Galaxy Note 20] H ow to hide the Status bar

Does anyone know how to hide the Status bar and display everything under the camera hole like this.
As on S8/S9, Note8/Note9 just needs to use the command: settings put global policy_control immersive.status=* is done
But for models with this android camera hole when using the above command, the screen containing the hole camera will be a black strip.

"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",

You can use System UI Tuner on the play store to get rid of the status and navigation bars on whichever apps you want. Just need to do a couple of adb commands to make it work.

Guess I never noticed it as I use dark mode and a black wall paper.

Enabling full screen app support for the particular app in settings>display has gotten rid of the black bars for me

You can use Nova Launcher to hide Statusbar.

Use Fine lock, Install Quick star module

in quick star model is no choice to hide statusbar

Do you know the Nova Launcher? Search in Google Playstore. With Nova Launcher you can also hide Statusbar via Gesture.

Good Lock. QUICKSTAR still works.
Hide clock first then turn off every icon like wifi and data.

Samsung's GoodLock NavStar module will show/hide the status bar.

This is what I did and it works.
1. System tuner ui to hide status bar.
2. Enable full screen app support in settings>display
3. I want to give credit to whoever figured this out, but don't remember. Get goodlock and install multi-star. Scroll all the way to the bottom of multi-star and select (the app size stretch to camera hole). Set the app to overlap the camera area.
That's it. No more status bar and it will look like the target picture. All apps.

It didn't work for me. It pushed everything up and cut the top off.

Question Avoiding burn-in on status bar?

Is there any way to hide the status bar icons? Specially the clock and battery indicator so we can avoid burn ins? Had burn-in issue on my mi 9t pro so Im not gonna take any chances...
I was easily able to hide the icons on my rog phone 2 but it seems that miui is blocking that method(having all these features, it's such a shame it still doesnt have the ability to hide status bar icons!)
Does anyone have any other way to do this?

SystemUI Tuner! https://play.google.com/store/apps/details?id=com.zacharee1.systemuituner
Its a nice app
You can grant the necessary permissions with either Root or ADB.

The clock, yes I think so. But I don't know about Battery, I'm not able to check it right now

Maybe not the answer you want to hear
I use HavocOS - there you can hide all status bar icons. I do it so, but only because I don't want to disturb my home screen with these icons
For the battery status I use a thin line on the top of the screen (it's a feature of Havoc), which changes the length and the color depending on the battery level... you can choose color #1 (fully charged) and color #2 (empty). I picked 2 colors (black for #1 and gray for #2), so that this line only appears when the battery is at about 30 %. Really nice

I gave it a try it's able to remove left hand stuff and some of right hand stuff.
Still I'd like to have something that whould hide my status bar and show it on slide like it used to be in older phones.
Anyways still better then nothing.

What Launcher do you use? On Nova Launcher you can hide the statusbar.

MIUI doesn't support Fullscreen Gestures on any Third-Party Launchers.

Don't bother, you re gonna swith to another phone anyway before it gets burn in. Or you can always replace the screen under warranty since burn in is coverer by xiaomi.

Really shame that MIUI doesn't allow to hide status bar.

Question Any ROM/Magisk Module/App to expand apps past hole punch?

Thread title, really.
I've missed immersive mode on my 7 Pro ever since I got my 9 Pro, there wasn't any time I would ever turn it off on my 7 Pro and it's why I'm keeping it on Android 10. But Android 11 lacks immersive mode so I can't use it on my 9 Pro. I fear burn in so I've had my status bar permanently hidden (set to 0px) and I just bring it down with a gesture when I need to view notifications.
But even though the status bar is 0px, all my apps still know the holepunch is there and push the content below the holepunch / make a black bar above the holepunch. Is there any setup that you guys know of that ignores the holepunch? Bonus points of its on a per-app basis. I know Samsung phones can use Good Lock to accomplish this, and it's crazy that a phone that doesn't even need root can accomplish this but I can't seem to find a solution for my phone with an unlocked bootloader lol.
But yeah, I really just want a way to force apps to ignore the holepunch. Anything?

That's what I'm using to force my status bar to 0px. Unfortunately the whole ignore holepunch thing doesn't seem to work on OOS11. Unless you found some way?

Did you enable this in Dev Settings? It appears when you are using G-Visual mod

Yeah, but even after enabling, it only affects the status bar and no other app. Even in your screenshot, I can see your settings app pushed considerably below where your status bar is. Seems like a true immersive mode is just impossible on Android 11

Oh sorry I misunderstood you, the G-Visual mod makes the app go full screen (with status bar) in portrait mode.

Themes / Apps / Mods Get the best multitasking/tablet experience

G'day everyone, just wanted to share a way to get awesome multitasking to get a nicer experience as a "tablet".
There's an app in the Galaxy store called GoodLock.
In the app is a heap of outstanding customisation tools you'll love. One particular one is called NavStar. It replaces the taskbar at the bottom on your screen with a "Task Stack". It's essentially a long list of all your currently running apps and interaction works the same way as the default taskbar... drag and drop an app from the Task Stack to the screen.
Instead of having only 8 apps in the default taskbar, the NavStar Task Stack shows all running apps, much like a desktop computer, for a much better multitasking experience.
On the inside screen, the task stack is shown next to the nav buttons. It disappears on the cover screen and only shows the nav buttons. Then checkout the GoodLock app called HomeUp... you can customise the entire multitasking interface (I have recent apps shown in a grid).
The only downsides are you can't use nav gestures with the task stack, and there's a bug the dev needs to sort out where when you rotate the screen, the stack disappears and you have to swipe the notification centre down to show the stack again. If youre using the cover screen then unfold it, it also disappears. I have a fix for it further below.
Now there are 2 tweaks for the task stack I've sorted out. One unfortunately requires root.
The first one is to get a tablet UI. It requires rooting and installing the Magisk module MagiskHide Props Config. Using this module, you need to change the build prop "ro.build.characteristics" value from "phone" to "tablet.
This gives you the date in the statusbar, a nicer/different notification centre and probably a couple over things I haven't noticed yet.
When done, it also gives you the task stack on the cover screen... that's the biggest reason I'd say to do this mod if you root.
If you set the nav buttons on the left hand side of the screen, you will get all 3 buttons and a couple apps in the stack on the cover screen. If you set the buttons on the right, the cover screen stack will show a lot more apps but the only nav button that will show is the back button on right hand side.
To get around this (if you want your buttons on the right), I have an app called Gesture Control. This way, I can have my nav buttons on the right which then allows me to use the back button on the cover screen to go back and use swipe up gesture to go home and swipe up and hold to access recents.
I also have a macrodroid task set up to disable the gestures on the inside screen (I don't need gestures as I have the 3 buttons) and enable the gestures on the cover screen.
The second tweak is using macrodroid/tasker to fix the task stack disappearing.
I have tasks set up so when the screen is rotated or the device is unfolded, a gesture pulls the notification centre down about 100 pixels then immediately back up in 50 microseconds... this shows the stack again and the status bar has a tiny little flicker you barely notice.
It's unfortunate that this bug exists and hopefully its fixed soon because it is an awesome desktop-like experience.

As an add-on to the above - in order to be able to display the Task Stack in NavStar you first need to go into the phone's Settings - Display and disable "Taskbar" there.
Otherwise the "Show Task Stack" option will be greyed out in NavStar.
