This started to happening after updating the driver to 270.41.06.
At first instance I thought that my video card was dying but after some tests I came to the conclusion that is either chromium or the driver.
For some weird reason, everytime I launch chromium, a lot of artifacts start to appear on the screen. It usually looks like this:
It get's worse through time and sometimes the desktop just freezes.
I can only reproduce the problem with chromium. I can use any other program, browser, etc. without problems, it's just chromium.
This is getting me crazy, cuz I need chromium.
I attached the log. Just in case, I'm using Arch x64 with KDE SC 4.6.2.
