Bug ID: 459206
Summary: All Plasma Desktop elements freeze entirely unless
mouse is currently moving. Wayland + Nvidia.
Classification: Unclassified
Product: kwin
Version: 5.24.4
Platform: Kubuntu
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: wayland-generic
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
When using the Wayland version of Plasma on Kubuntu 22.04, all desktop elements
will freeze if I am not currently moving the mouse, making the desktop nigh
unusable. The splash screen gets stuck almost immediately, context menus are
laggy and difficult to select options in, and if I swipe my mouse over my task
manager icons: The selected program will be two or three icons away from where
my mouse actually stops.
I've found two other users with the same problem so far, their specs are
included below. The main correlation is that we are all on 22.04 with an Nvidia
GPU. I myself am using the Kubuntu-Backports-Extra PPA which puts me on Plasma
version 5.25.5, but still face the exact same issue as the other users on 5.24.
Apologies if this is a Kubuntu bug rather than a KDE/Plasma one, I'll make a
bug report on their end if necessary.
STEPS TO REPRODUCE
1. Use Kubuntu 22.04 on a Nvidia GPU
2. Install plasma-workspace-wayland and restart.
3. Select Wayland in SDDM and login.
OBSERVED RESULT
Splash screen will immediately freeze upon appearing if the mouse is left
stationary. Right clicking and moving mouse on top of an item in the context
menu will leave the wrong item selected until the mouse is jiggled. Same for
the task manager.
EXPECTED RESULT
All items should animate as normal.
