SUMMARY When you have a transparent blur as background for e.g. the terminal or Dolphin and the drag transparency activated, the blur disappears while draggin and when you release it the transition from transparency to the blur is very ugly. STEPS TO REPRODUCE 1. Set a transparent theme and background with blur in e.g. the terminal 2. Activate window dragging transparency 3. Drag a window and release OBSERVED RESULT The transition is very ugly. EXPECTED RESULT The transition could be smoother. It seems like the effects are not stopped and reactivated independently. There should be some kind of waiting for one effect to deactivate and the other to reactivate again. SOFTWARE/OS VERSIONS KDE Plasma Version: 5.20.5 KDE Frameworks Version: 5.78.0 Qt Version: 5.15.2
Just saw you confirm this one. This bug is actually caused by the combination of dragging transparency and maximizing effects. If you turn of either one, it is fine. It seems like the maximizing effect is slowing down the transparency effects, which doesn't look nice. I have just turned of dragging transparency since I realized that.
