on ivy bridge HD2500, the same issue, random white stripes appeared very often.
on kernel 3.5.0.x (at least confirmed on 27, 28) and 3.2.0.x (at least confirmed on 40)
$ dpkg -l kde-runtime

I never get this issue on older machines with NV or ATI graphic card, the intel ivy bridge seems very annoying.
the picture shows the symptom, some application like the desktop, gimp, etc will always show these white stripes, if hover over the menu, it will show narrower stripes in the menu item area. Other applications like Kate, firefox, libreoffice, etc will not show these white stripes.
On live-cd the system still using KDE 4.8.3 seems stripe free. Can anyone confirm on this problem?

I had the same thing happen to me. Wow, I went to find my old post and see that you had already found it. Your attachment looks identical to the stuff I saw. I closed my 'view your posts' tab, but I think I stated the system updates cured the problem. You know, that icon on the task bar that says--hundreds of recommended updates available. I haven't seen one piece of info to indicate what the cause might be.

Would you please post the result of following commands, the result might be helpful?
Code: Select all
grep -A6 -E "LoadModule: \"intel\"" /var/log/Xorg.0.log
Here is my output:

Little late but here is output:

So, I guess you did fix it with the upgrade. Any idea exactly what the cure was?

U have almost the same kernel and xserver version, and I have a little bit newer ones. The only difference is the KDE version. I also did several tests with 3.2 kernel and much older xserver version like 1.11. The results are always the same: 4.8.3 and 4.10 were OK, the 4.8.5 had white stripes or even crash. So I guess this may due to bugs in KDE 4.8.5.
