With the reimplementation in 5.25 and the fix in 5.25.1, when you move windows between workspaces in the new Grid effect, they animate really strange. You drag a window to another workspace – this really drags its miniature preview – and drop it to this other workspace. This initiates a fast slipping process from its current workspace to the new. But you have just dropped it there! Instead of just appearing there, it animates like you never dragged it from its original workspace over to the other one.

EXPECTED RESULT
The window drops to the new workspace and is just appearing there. The old effect handled this with no explicit animation other than for an sudden new window in Grid (like when an error is appearing or such). It looked more natural than the current slipping between workspaces. Again: You have already dragged it there, it shouldn’t move from it’s original position!
