Bug ID: 511100
Summary: kwin_wayland 6.5.0 renders mouse cursor garbled and
unusable
Classification: Plasma
Product: kwin
Version First 6.5.0
Reported In:
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: wayland-generic
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
After upgrading from Plasma 6.4.5 to 6.5.0, the mouse cursor appears as a wide
streak of garbled pixels, rendering Wayland sessions almost unusable.
STEPS TO REPRODUCE
1. Be on Arch Linux, having the same hardware that I do
2. Upgrade the system
3. Initiate a Plasma session on Wayland
OBSERVED RESULT
The attached image shows the cursor to the left of the Virtual Desktops widget.
EXPECTED RESULT
That the mouse cursor is rendered correctly and that I am not required to
initiate an X11 session or downgrade Plasma.
SOFTWARE/OS VERSIONS
Operating System: Arch Linux
KDE Plasma Version: 6.5.0
KDE Frameworks Version: 6.19.0
Qt Version: 6.10.0
Kernel Version: 6.17.5-arch1-1 (64-bit)
Graphics Platform: X11
Processors: 4 × AMD A10 PRO-7800B R7, 12 Compute Cores 4C+8G
Memory: 16 GiB of RAM (14.6 GiB usable)
Graphics Processor: AMD Radeon R7 Graphics
ADDITIONAL INFORMATION
This is a fairly old processor with an integrated GPU that supports the radeon
DRM/modesetting driver. Despite its age, I have experienced no issues with it
until now.
I believe the problem is attributable to kwin_wayland because my SDDM greeter
is also affected in the case that I have the following sddm.conf option in
effect.
