Video of glxgears running
SUMMARY
I am experiencing a stutter or flicker that almost looks like it is re-showing
prior frames. Experienced it in Yuzu, freetube and glxgears(when framelimited).
When I tried to capture with Spectacle it didn't capture it in the recording.
Attached from my phone.
STEPS TO REPRODUCE
1. Run 'MANGOHUD_CONFIG="fps_limit=20" mangohud glxgears'
OBSERVED RESULT
flicker
EXPECTED RESULT
No flicker
