GUI doesn't scale on custom resolutions

[ViRb3]

Running OnePlus 5T here with OmniROM. I have disabled the navigation bar and I use gestures. The GUI (at least version 2.2) has a black bar on the bottom, which is a result of the odd resolution that my phone has with nav bar disabled. There is an AndroidManifest property that can be added to solve this, trying to find it right now. Most ROMs will scale no matter the availability of this property, but OmniROM and some others don't.

You could try to report OmniROM, hopefully, you get an answer from them.
I don't make any mod, can't tell what customization will break which part of the system, sorry about that.

The black bar is expected AOSP behavior which most custom ROMs override by default. Sadly, OmniROM is not one of them, but it is still not an issue with the ROM.

I think this is what you need:

https://developer.android.com/guide/practices/screens-distribution.html
android:resizeableActivity true
Looks like resizeableActivity defaults to true if targeted API > 24.

Or, alternatively:
API >= 26:
<meta-data android:name="android.max_aspect" android:value="5.0" />
API < 26:
<activity android:maxAspectRatio="5.0">

I don't have time on the project. You might like to download the GUI code and try it out on your device.
