Window position incorrect after restoring from fullscreen mode
After returning from fullscreen mode, the window position of the restored window is changed: the window is about 20 pixels moved to the left and the top.
To reproduce, open a browser, e.g. Chromium, press F11 to go to fullscreen mode, and return by pressing F11 again. Do this several times in a row. The first time, the window position of a maximized Chromium window still seems correct, but every other time you can see the window move up and left.
