Hello all, this topic seem to be all over different forums and bugtrackers, but there hasn’t been any progress for (seemingly) years…
As I’m trying to use a laptop with dual GPU (intel+nvidia 980M), running opengl/vulkan things with xwayland produces artifacts of phantom frames popping in from the past. (as if frames go like 1 2 3 4 5 6 3 7 8 9 6 … ) resulting in horrible jitter. (was testing with unigine-heaven)
So far from all workarounds i’ve geathered only one worked - setting __GL_MaxFramesAllowed=1
But it drops performance up to 25%, and doesn’t seem to work for vulkan applications
So what I’m wondering is - are there better (maybe nixos-specific) workarounds?
(tried forceFullCompositionPipeline - no effect, tried __GL_YIELD=usleep, tried XWAYLAND_NO_GLAMOR - no effect)
