windows invisible at random times

[zeruke]

Binary package hint: compiz

this happens randomly were i start a program and its on top but doesn't show any of the visuals of that window.... it does seem that it might be related to https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/498113 but im not sure.....this happens to me on the default desktop of natty with unity enabled, and if i have it were compiz is on when using the unity2D set up....it has yet to happen with the classic desktop.

right now it seems this starts up when opening a pdf which opens document viewer....and i have all of the updates for natty

the pdf iv been trying to look into usually when this starts up is the Unity_Architecture pdf seen at https://wiki.ubuntu.com/Unity?action=AttachFile&do=view&target=Unity_Architecture.pdf
