Recording of the graphical glitches
SUMMARY
When connecting to a remote VNC server on Wayland, the mouse cursor visually
glitches, producing white outline. This outline visually changes even while not
moving the mouse.
STEPS TO REPRODUCE
1. Start krdc from Wayland
2. Connect to a remote machine using VNC (I didn't try other protocols)
3. Move mouse or just keep it still
OBSERVED RESULT
The mouse flickers with white outline.
EXPECTED RESULT
The mouse is clear as when using X11.
SOFTWARE/OS VERSIONS
Linux: Linux 6.9.9-1-MANJARO (unstable branch)
KDE Plasma Version: 6.1.2
KDE Frameworks Version: 6.3.0
Qt Version: 6.7.2
ADDITIONAL INFORMATION
System is an Nvidia Prime setup, with primary AMD GPU/CPU and dedicated NVIDIA
GeForce RTX 3080 Laptop GPU.
Using proprietary Nvidia drivers, version 555.58.02.
This problem is not visible on recordings done using Spectacle. It is, however,
visible on recording done using OBS (attached).
This problem does not happen when using X11; only when using Wayland.
Happens both when scaled and on original resolution.
