In my case I can see the content of all the windows, in fact I see all windows from all desktops, but no black rectangles. I've been trying to isolate the cause but so far no luck. Sometimes it happens when I get a notification, other times it happens when I switch windows with alt+tab and once it happened just by using the open file dialog (which shows a pop-up with the possible file names). -- You are receiving this mail because: You are watching all bug changes.
