@davefury , because this is not a bug of compiz, so disabling window animations is a workaround only to the extent it doesn't trigger the intel driver/xorg bug while opening windows/menus. Other software that use the graphic card is still capable of triggering the bug, for example I was able to crash xorg while playing a video with totem.
