Screen flashes during exit from full screen mode #668

Open Polymorn opened 3 years ago

Polymorn commented 3 years ago

Describe the bug An error occurs in application frame while user turning off full screen mode. Flickering effect occurs for a split second.

To Reproduce Steps to reproduce the behavior:

  1. Open any image
  2. Press F11 to turn on Full Screen mode
  3. Press F11 again to turn off Full Screen mode
  4. Do step 2 and 3 until you see the error. This effect appears in about a third of all cases.

Expected behavior Smooth transition from full screen mode to standard view without glitches and flashes.

Screenshots The effect lasts for a split second. Attempts to capture it were unsuccessful.

Desktop:

Additional context I think that this effect appears due to the wrong offset of the application frames while application is returning to standard view.

This is quite apparent if the normal window is maximized. When leaving fullscreen, the window goes to normal state then animates to maximized state (3.17 also affected).
