On Windows 10, when I open the Task Manager, instead of the Wobbly Windows animation on movement, the window diseappears, and reappears when the mouse button is released. But only in situations, when there is no other window (e.g. File Explorer) open - if the latter, then also the Task Manager window is animated without issue.
EDIT: WindowFX 6, also Fences 3 and ShadowFX active.
EDIT2: Well, the issue is gone after a shutdown and reboot...
