It would appear that on my system, small 32x32 GL_RGBA textures used for
borders around window previews get corrupted after a suspend/resume cycle

Reproducible: 100%
 1) enable that compiz is running and windows preview plug-in is enabled
 2) ensure window previews show up when mouse over window list applet
 3) suspend to RAM 
 4) resume from suspend
 5) mouse over the window list applet
 6) you will notice the border and shadows are not properly rendered



Tried to follow the instructions here
