Created attachment 145746 [details] Screenrecording SUMMARY Please see the screen recording. SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE Neon Testing KDE Plasma Version: 5.23.90 KDE Frameworks Version: 5.91.0 Qt Version: 5.15.3 ADDITIONAL INFORMATION Wayland Scaling 2.0 Breeze theme
I can confirm this happens on any scaling above 100% on Wayland. I also tested with Xorg and I couldn't reproduce the issue. It's Wayland-specific. I also noticed the icon looks much blurrier with scaling on Wayland. On X, where the bug doesn't happen, the icon looks crisp. The animation is probably not getting scaled properly on Wayland.
