After installing new graphics card (MSI R6850 CYCLONE 1GD5 PE/OC), latest drivers on WinXP 32bit, I'm experiencing frequent drawing artifacts with Mozilla Firefox 8.0 and Mozilla Thunderbird 8.0. The problem represents itself either as horizontal black stripes or scattered color checker pattern. It happens especially when switching from other application to Firefox or Thunderbird or when swiching from child window (like Download Manager) to Firefox. It affects either whole application or just some rectangular region (clearly region which was redrawn due to application switching). Next repaint (like switch between Firefox tabs) usually fixes the problem. It is just visual issue, behavior is not affected. The problem never happened to any other application till now. Any ideas? Anyone experienced same problem? Thanks in advance.

P.S. Here are the screenshots for both problems:

Try to disable hardware acceleration.

If disabling hardware acceleration works then check if there is an update available for your graphics display driver that fixes these problems.

Thanks for advice. Disabling HW acceleration indeed seems to got rid of the problem (at least I haven't seen it since). I'll check drivers on regular basis - but just now, I have latest & greatest.
