Good to hear, thanks. True, the actual call to glXBindTexImageEXT() etc was cut out from the example. Sorry for the confusing subject line.

Default Re: Huge memory leak with texture_from_pixmap

This issue will be resolved in the next driver release.

However, I should note a few things about your test app. Trying to redirect unmapped windows combined with a bug in the X server (it returns the screen pixmap when an app tries to redirect unmapped windows, see freedesktop.org Xorg bug #9129) plus the lack of an error check for multiple GLX drawables referring to one X drawable in the nvidia driver led to this crash.

Fixing any one of the above problems will avoid the X server crashes, but you should really avoid redirecting unmapped windows in your composite manager to get the result you want. Otherwise, you're going to see X errors whenever you run this app on a fixed X server or a fixed version of our driver.

Don't know if helps, but i'm using Beryl + nvidia-drivers-1.0.9742 + Gentoo 2006.1 + Kde 3.5.5 and i've also noticed huge memory usage, from both Beryl and Xorg. After a few day of continuous activity my X just crashes and memory goes back to normal levels and the cycle starts again...
My video card is an onboard Nvidia Geforce 6150.
