Every time when i launch Blender (2.43, 2.44), it works for 10-15 seconds, then the 'default cube' disappears and after 10-15 seconds screen is filled with artefacts. I can only shutdown X manually (keyboard shortcut). X.org logs are clean..
I'm using Compiz&Beryl, but if i start 'clean' X, the whole scenario is repeated with a system-halt in the end.
I really don't know if this is blender's bug or fglrx bug, but i've never encountered it before with other applications.
OS: Ubuntu Linux, kernel 2.6.20-16-generic, 32-bit i686 platform.
Here's my fglrxinfo:
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: Radeon X300/X550/X1050 Series
OpenGL version string: 2.0.6747 (8.40.4)

There is the problem. Eye candy window managers do not work well yet with Blender.
When Compiz and Beryl are more mature, no doubt the situation will change. Until then do not use them together.

"but if i start 'clean' X, the whole scenario is repeated

It seems eye candy wm are not the fault this time. Being
a X300/X550/X1050 (RV370?) he could try the Xorg DRI radeon
driver, tho R3xx had (has?) some other issues like line
stippling and moving from one driver to another can be
tricky if things point to wrong files. Do at your own
risk (use a really recent livecd to test?).

Leonardo: some things to try are reducing color depth and allocating more video memory. Here is a man page to read:

Muchas gracias!

With Dri 0 (= false = no) you just disabled 3D acceleration,
I would not call that a fix. Maybe even the issue is a
different one than the original (ATI card, fglrx driver
vs Intel integrated video, Xorg intel driver).

This is a generic request to test your bug report and see if it is still an issue in 2.5alpha2 if so please let me know by making a comment in this report ie 'also in 2.5alpha2' and I will add it to the 2.5 bug list.
