I just booted up Blender for the first time (which, inherently, makes me a Blender n00b, so have pity) and I’m having some graphics problems. First of all, I know it is supposed to cover the taskbar, but I don’t want it do, and while I read how to solve this issue in Windows, I don’t know how in Kubuntu.
More importantly, windows behind Blender bleed through, sometimes just a line or two but often the entire viewport is Firefox or somesuch.
I have a Radeon 9000, so I’m using the open source ATI drivers with Mesa. The “solutions to common problems” mentioned something about this, but not how to remedy use with Mesa. Any ideas?
I’m really eager to apply my 3DS Max skills to Blender, and so I hope this works out 
Thanks!
Also, running that little python script to find vendor didn’t work (the python console remained empty…) but here is glxinfo |grep vendor produces:
$ glxinfo | grep vendor
libGL warning: 3D driver claims to not support visual 0x4b
server glx vendor string: SGI
client glx vendor string: SGI
