@mythmon I’ve seen you have this issue before with Minecraft
The flickering is caused by the lack of explicit sync on Wayland with Nvidia drivers.

Both the wayland-protocols merge request and the v555 Nvidia driver are required in tandem to remove flickering.
The merge requests will also (hopefully) fix any flickering you experience on Electron applications.
when will it be integrated into nixos?
oh wow! I’ve been waiting for this for so long I’ve given up nvidia+wayland combination, seeing how some discussion threads date back 4-6 years ago
P.S. oh, i even remembered I’ve posted a question about it in this forum: XWayland+Nvidia jitter mitigation question
workaround was to use __GL_MaxFramesAllowed=1 that caused terrible performance drop and still did not fix missing redraws in programs that called redraw on certain events only
