555.42.04 is working sort of well with KDE Plasma & Wayland, but noticing 3 issues with my RTX 4080:

  1. Significant frame rate drops when running out of VRAM, probably closely related to or same as VRAM Allocation Issues
    only happening in demanding games and 4K resolution, especially Hogwarts Legacy, monitored using MangoHud when VRAM usage is at 100 %. Framerates dropping from ~ 80 - 100 fps down to 25 or even less, making the game unplayable. Restart required.

  2. When using the open source kernel module, I see lots of messages: kernel: NVRM: nvAssertFailedNoLog: Assertion failed: pEventNotificationList->pendingEventNotifyCount == 0 @ event_notification.c:289. Doesn’t seem to cause any issues though. Not seeing this with the proprietary module, otherwise both modules open and proprietary behave more or less the same.

  3. Turning on VRR sometimes causes a black screen / flickering, no issues with VRR turned off.
