Usually it's when activating and then rapidly retriggering the same edge to deactivate the effect. Upon deactivating PresentWindows, I get no animation, return to the app to find the compositor has crashed. Sometimes it starts itself, sometimes I need to manually turn it back on. 1957432 2 nate 2020-09-14 20:32:43 +0000 *** This bug has been marked as a duplicate of bug 423319 ***
