Lets say you have a dual screen (a and b) setup: |----------||----------| | A || B | |----------||----------| Dragging any window from A to B works just as intended. Dragging any window from A to the TOP* of B and release is where the animation behaves weird. It is then animating the window as follows upon release: - the window instantly pops back to the initial position it had before dragging in screen A - the window then animates towards the desired position on screen B Note, i already had it dragged to B. * i say "TOP" but i mean any of the snap positions. To be clear, by TOP i mean dragging your window to the utmost top to make it fill all the screen space on release. I don't know how it's called. I hope the kwin devs just know what i mean by this :) Reproducible: Always Steps to Reproduce: see above Actual Results: see above Expected Results: It should not move the window back to a and animate to b. It should keep it on the dropped position and animate to - in this case - maximized state.
