Was going to post this today. I am currently testing 25.04 with the 570 driver. On X it works perfectly and all games run beautifully. But when I changed to wayland, there was huge input lag, latency and even freezing when on the desktop (It worked inside the game, although the game lost a chunk of FPS on wayland versus X). Is there a way to grab information about why wayland would freeze (and unfreeze if I ALT+TAB between apps, to then freeze again later).
My test was because HDR came out, so I see it shows when using wayland but it is not good for typical workflow or gaming yet based on what I just went through. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2081140 Title: Poor performance in Nvidia Wayland sessions Status in mutter package in Ubuntu: Triaged Status in nvidia-graphics-drivers-560 package in Ubuntu: Won't Fix Bug description: On a desktop with a single Nvidia GPU and single monitor, desktop performance is poor in Wayland sessions. The main culprit seems to be that all rendering gets deferred until meta_drm_buffer_gbm_new_lock_front by the Nvidia driver, which blocks the main loop at a time we are not optimised to handle blocking.
