KDE 4.6 Graphics Glitches / Screen Refresh Bug Fix for Intel/GMA VGA Card

The redraw of many widgets when using the KWin doesn’t work correctly:

  1. In Firefox if I scroll down the page, the page is not redraw correctly. I have to move the mouse all over the page to remove the broken text.
  2. Shell window is not updated properly

If you have experience these symptoms with KDE 4.6 under Ubuntu 10.10 Maverick Meerkat with an Intel graphics card, then there is a quick fix:

sudo add-apt-repository ppa:glasen/intel-driver sudo apt-get update && sudo apt-get upgrade

It fixed it for me at least.
My intel graphics card on Asus U35JC:

00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 18)
