Description Podagric 2021-12-17 12:43:48 UTC

STEPS TO REPRODUCE
1. Disable the minimize and/or open windows effect
2. Open a window

OBSERVED RESULT
The shadow will be displayed at kind of two different times, first it appears instantly, as it should be, but then a kind of effect is applied over it to make it stronger

EXPECTED RESULT
Since the effect is turned off then it doesn't make sense to have an animation in this scene. I would expect the window to simply appear and no effects to show.

SOFTWARE/OS VERSIONS
Operating System: Arch Linux
KDE Plasma Version: 5.23.4
KDE Frameworks Version: 5.89.0
Qt Version: 5.15.2
Graphics Platform: X11

ADDITIONAL INFORMATION
1. It is possible to work around this by setting the speed of the animations to maximum, but with that the other effects will be lost.
2. Decreasing the size and strength of the shadow is also helpful, but it lowers the contrast between the focused window and the ones open in the background
3. I slowed down the animations while recording the video to make it sharper.
