example of an empty/transparent firefox window
I have noticed lately that on resume, if I have firefox maximized that it will
resume with only the title bar and the actual window is completely transparent.
I have attached a screen shot. In this instance, the Firefox window on my other
(primary) monitor (with a panel) was fine and rendered its content correctly.
Usually resizing/wiggling the window "fixes it". This time I just left it there
after the screen shot, and, while filling this out it eventually painted
itself. However, it also unpainted itself and repaints kind of randomly (at
times now, the upper right quadrant had painted content, and the rest of the
window flashed transparent.
I have also noticed that the new hover preview is really messed up after
resume, too, mainly around firefox. Going over previews really seems to trigger
things and causes Firefox to flash/go transparent.
