Video showcase of the bug
Here is a trace file and a video showcase of stuttering in Feral game launcher (OpenGL) that happens in many cases, but not reproducable in all GL apps/desktops (mGBA emulator, Godot game engine, Feral launcher)
I'd like to see one of AMD OpenGL developers take a look at the trace file and a video for proof that stuttering actually occurs and try to figure out what might be causing the issue.

PS to any of the developers: If you guys think that I should post this bug somewhere else (etc. MESA bug tracker) plz let me know with a response.

Video showcase #2 in 60fps, much more obvious
I add a capture in 60fps so the issue is much more noticable by the bare eye
I just spoke to another user that has different model of the RX 5700 XT and he doesn't seem to be having this issue.
