--- Comment #26 from Roderick Colenbrander thunderbird2k@gmx.net 2007-10-31 07:15:16 --- You guys indeed have two different problems. In case of Michael I don't think opengl is set up correctly: Xlib: extension "GLX" missing on display ":0.0". err:wgl:X11DRV_WineGL_InitOpenglInfo couldn't initialize OpenGL, expect problems
That can indeed lead to the video memory issue.
The other issue is indeed related to PBOs. It is one area I need to clean up but I need to wait until Stefan his surface rewrite is done.
