Thanks, based on this and Maarten's assessment, I think we can agree that this
is a low priority, especially since this is happening ONLY on GLK which is a
low power device usually used only by tablets, IVI systems, ... which do not
use a cursor :D

NUCs are the exception, but one does not usually change resolutions in a
desktop PC.
