Created attachment 186001 [details] Video of issue SUMMARY With animations in system settings set to defaults, activating split view shows an animation and the extra view from splitting slides into place at half the width of the current view real estate. When changing the animation settings to "instant" (disabling the animations), activating split view then opens the second view with a very small width. STEPS TO REPRODUCE 1. Open system settings to "animations" page 2. Reset settings to defaults (or change the "global animation speed" to any non-instant speed) 3. Open dolphin, close split-view if already activated 4. Activate split-view in dolphin 5. Observe the slide-out animation plays and the split-view is the correct width 6. Close the split view 7. Move back to system settings animations 8. Set the "global animation speed" slider to the right (instant) and click "Apply" 9. Switch to dolphin and activate split-view OBSERVED RESULT Split-view is opened with no animation played, but width is very small instead of being correct. EXPECTED RESULT Split-view is opened with no animation played and the width is the same as when an animation is played SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.4.5 KDE Frameworks Version: 6.19.0 Qt Version: 6.10.0 ADDITIONAL INFORMATION Video attached showing issue
This animation apparently counts on the duration of the animation without taking into consideration its variation. Nice find. That's easy to fix :)
