Package: kde-window-manager
Version: 4:4.6.5-2
Followup-For: Bug #640799
As the link (http://www.phoronix.com/scan.php?page=news_item&px=OTM0NA), given
by Martin Steigerwald on the debian-kde mailing list (
http://lists.debian.org/debian-kde/2011/08/msg00070.html), says this bug
affects all Intel graphic cards.
My laptop does not have sandybridge architecture and has been affected by
this problem. I also have a desktop with Intel chipset at work that has been
affected. Both machines are running Debian testing.
The fix given works fine on my laptop, however on the work desktop
everything gets slow. I installed Debian on that desktop this week so I
don't know if it is slow 'cause of this bug or some other factor. On the
laptop kwin has worked fine for years now, so all I had to do was to set the
environment variable and everything is back to normal.
This mail has been written from my laptop, here's the system info:
