Dear Dotan,<br> The problem of flashing/flickering in 3D apps/ videos with Xv enabled on account of non-redirection is limited to AIGLX and not an issue at all with XGL and compiz. fglrx till date has many mem leaks and crappy 3d performance on linux especially with compiz enabled. If you want to use these apps with compiz, for now use XGL. Else just disable compiz temporarily when you use them under AIGLX until DRI2 stabilizes and all drivers incorporate the changes in the rendering infrastructure. (PS: Fusion icon allows you to easily enable/disable compiz)<br>
