SUMMARY On Plasma 5.23 and 5.23.1, changing the animation speed has no effect. The animation speed stays the same no matter what. Tested on Wayland, not tested on X11. STEPS TO REPRODUCE 1. 2. 3. OBSERVED RESULT EXPECTED RESULT SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: 5.23.1 KDE Frameworks Version: 5.87 Qt Version: 5.15.2 ADDITIONAL INFORMATION Archlinux
Ran into this behavior in an earlier version of KDE, it may be due to a hardcoded value in ~/.config/kwinrc. This manual edit worked in my case: https://bbs.archlinux.org/viewtopic.php?pid=1958589#p1958589
Yes, deleting the line "animationDurationFactor" in kwinrc works. Thanks !
