Steps of reproduction

1. Enable rounded corners
2. Open a window
3. Close a window

or

2. Change workspace
3. Change workspace again

Expected behavior

No shapes or shadows

Current Behavior

Like in the video, square-like shapes in the corners when the windows are fading

It gets fixed with --experimental-backends but now the shadows are looking like this:
