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.

My setup:
OS: Pop!_OS 19.10
CPU/RAM: Intel i5-6600 / 16 GB DDR4
GPU: Sapphire Pulse RX 5700 XT
Kernel: 5.4.0-999-generic (Ubuntu daily)
MESA: OpenGL version string: 4.5 (Compatibility Profile) Mesa 19.3.0-devel (git-ff6e148 2019-10-29 eoan-oibaf-ppa)
