This bug is not limited to changing the scale from lower to higher and is not limited to shadows displaying garbage. It also occurs:
* when changing the scale from higher to lower * infrequently when new windows or dialogs are created, particularly snap apps like nautilus or gnome-text-editor or modal dialogs such as e.g. evolution Other effects in addition to shadows displaying garbage are: * the window not capturing mouse events correctly, other windows below the garbage window capture the events * the window not being able to capture focus, i.e. come to the front of other windows The situation can be 'fixed' by maximizing + unmaximizing the window, users can TAB-select the window if it cannot be reached with the mouse.
