This bug will occur occasionally where Mutter will draw the shadow of a window, but the window borders and such will appear either incomplete, or they will not be drawn at all. Attached is one example I managed to capture with a screen print (sometimes PrintScreen doesn't capture the corruption). It's the bottom half of a dual-monitor setup, of which the top half is irrelevant. I completely removed Unity and Compiz, and Gnome-Shell is running (almost) perfectly, save this annoying error. Can someone tell me why this is happening and/or how to fix it? Thanks in advance.
