(In reply to Michel Dänzer from comment #26) > It's a kernel issue, not an xf86-video-amdgpu one. Thanks for clarifying. I could also reproduce this issue with Doom OpenGL in Steam Play/Proton 4.9. As soon as I move the mouse enough, there are frametime spikes (the red ones in the "total" graph): https://abload.de/img/screenshot_20190710_26sk21.png When I turn off pageflipping in xorg config, the red spikes there are gone: https://abload.de/img/screenshot_20190710_2k7k67.png Luckily, the Vulkan renderer of the game doesn't show the issue. But it once again makes clear that this bug can affect a wide variety of software in Wine.
