NVIDIA Wayland
Classification: Plasma
Product: kwin
Version First 6.6.5
Reported In:

An strace log of the behavior, when logging the freeze stops the tiling UI from
appearing at all
When opening the tiling menu, the mouse cursor abruptly freezes and there is a
massive lag spike before the tiling UI opening animation plays normally.
STEPS TO REPRODUCE
1. Move cursor on desktop
2. Open tiling UI while cursor is in motion (Meta+T or configured shortcut)
OBSERVED RESULT
The cursor hangs for a brief second before the tiling menu opening animation
plays
EXPECTED RESULT
The tiling menu should open normally
SOFTWARE/OS VERSIONS
Operating System (available in the Info Center app, or by running `kinfo` in a
terminal window): NixOS 26.11
KDE Plasma Version: 6.6.5
KDE Frameworks Version: 6.26.0
Qt Version: 6.11.0
ADDITIONAL INFORMATION
Logs I took show the main thread hangs for 1-2 seconds on every tiling UI open,
other KWin animations and window operations work smoothly. Only the tiling UI
triggers this freeze. Happens consistently on every open, not just first time.
