I think I found a correlation. Games that limit their framerates (for example,
Sonic Frontiers or NFS Hot Pursuit Remastered being engine locked to 60fps)
somehow make the display's refresh rate vary. Severity depends on the game,
varies between a hitch every second to constant variation in display refresh
rate. Locking the display's refresh rate to 60 for these games fixes the issue,
but it's tedious.
I am using Arch Linux, Mesa RADV driver version 22.3.2-3 on an RX 5700, KDE
Plasma 5.26.5. This happens both on Wayland and X11. VRR is set to
automatically apply on Wayland.
Not only does this cause display brightness flicker, but also extremely uneven
frame pacing.
