If you have a fullscreen window and move it using Alt+Left mouse, the quick (un)maximizing is triggered. This is usually not visible but when using the new Maximize effect, you can see that if your window is maximized and then you fullscreen it and move it around, that the maximize animation is triggered. See Review 107050 Reproducible: Always Steps to Reproduce: 0. Have the Maximize effect enabled 1. Open a window 2. Maximize it 3. Fullscreen it 4. Press Alt 5. Left click and hold the window Actual Results: The window jumps to its original size and then transitions back to fullscreen Expected Results: Nothing, you can just move the window around to any other screen
Created attachment 74857 [details] patch preview applied is a patch that omits _all_ special alteration of maximized fullscreen windows (what should be correct, since you can only move the window between screens anyway)
