Comment 26 for bug 194638

I'm using Fedora 11, this is my problem too on my GeForce 7600 GS (256Mb of RAM). It's not Ubuntu specific.

Current versions:
Xorg 1.6.1.901
Nvidia driver 185.18.14 / 180.51
Kernel 2.6.29.4
Compiz 0.7.8
i686

My previous Fedora 9 _working well_ on the same hardware, there's:
Xorg 1.5.2
Nvidia driver 177.82
Kernel 2.6.27.24
Compiz 0.7.6
i686

I have to open many windows to trigger the bug (~10-15 firefox). If I switch to another VT and back / restart compiz with --replace / kill some windows, then I can play videos with XV for a while (5-10 minutes). ALT+TAB in compiz is much slower when the XV doesn't work.

Daniel, I cannot found a method to check used texture memory, googled for hours for nothing.
