When using Taskbar (whether in conjunction with SecondScreen or not), the "usable" aspect ratio appears to be set incorrectly
There appear to be 2 separate (but likely linked?) issues:
1) The usable space on the screen is incorrect
2) The width of the Taskbar itself is sometimes set incorrectly
Issue 1: Usable Space
The external display's usable space seems to be using the phone's aspect ratio, leaving bars of unusable space along the top and bottom
The "default" wallpaper displays in this area, underneath the Taskbar wallpaper
Apps can be opened and dragged into the unusable space, however the contents of the window kinda 'stops' at the top and everything past it (outside of the Fullscreen and Close buttons) is just a black rectangle
Fullscreening apps makes the full background go black, but none of the contents will expand out of the 'usable space' (so for example a "fullscreen" youtube video looks like what happens when you watch a 16:9 video, rendered out to 4:3 with the black bars, on a 16:9 screen - it only takes up the middle portion with wide black bars on all sides)
The Taskbar is (almost) always aligned with the bottom of the usable space, rather than the actual screen (though the Android NavBar is correctly at the bottom as expected)
Issue 2: Taskbar Width
The width of the Taskbar is sometimes only ~2/3rds of the screen
When this happens, opening apps in "fullscreen" sets them to the (reduced) width of the Taskbar, while also sending the bottom portion of the window below the usable space (where it's impossible to interact with anything)
Whether the Taskbar is full-width or the reduced one seems to happen at random
I don't remember having either of these issues on Android 11, but after OnePlus so kindly forcibly updated my phone to A13, this has been consistent
I'm assuming that A13 support is "experimental at best" at the moment(?), however if anyone even just has ideas for ways to work around this (I have Root, and already enabled the additional ADB settings in Taskbar) that would be a big help!
