Window decoration in subsurface that stays visible after minimizing window
If subsurfaces have parts that are visible outside the area of their parent shell surface, these parts will not get proper damage and thus have improper contents on some occasions.
* minimizing windows
* switching between windows
but there may be more.
To test, move some subsurface outside the window area in clients/subsurfaces.c, e.g. add some arbitrary x/y offset to a widget_set_allocation call in resize_handler.
Another problem just popped up that might be related:
If an application (un)maximizes without changing its size (which is a legal thing to do, especially on unmaximizing weston provides size 0x0 so it's perfectly valid to just keep the size the window had when maximized), the actual (un)maximization which moves the window position will not be visible until the pointer is moved over the main surface.
