this happens randomly and i can't do a crash report on this, because i actually think it does not even really crash, but it blacks out and the widgets are not getting drawn anymore. yet accessible. see screenshot, when i access the startmenu i just get a white widget. only exit is to press the reset button Reproducible: Sometimes http://s28.postimg.org/cpnivfjql/20140920_133754.jpg
Created attachment 88761 [details] screenshot taken with camera
Does pressing alt+tab fix it?
