Every once in a while the right click menu is leaving around one of its items:
This bar sits on top of everything and the only way I can find to make them go away is to change something in the screen setting (e.i. move the alignment of my monitors a few pixels) to force a full redraw. This just started a week or so ago and I've made no hardware updates and /I/ didn't do anything with driver settings or the like.
Any ideas what might have changed or how to make it go away?
