Created attachment 628565 [details] artefacts on xchat and firefox Description of problem: My vga has always been problematic (I had similar issues on RHEL 6.1 in the past) and it was fixed in xorg-x11-drv-intel so I believe this will be also problem on drivers. So far this issue happens after having laptop turned on for multiple hours (like over the night ....). These artefacts starts to apper on gnome-terminal, xchat2, sublime text editor, firefox .... Desktop works fine for few hours (like 6) after the reboot. This is happening since the release of f17. Sorry for not reporting it earlier. Version-Release number of selected component (if applicable): $ lspci -nn | grep -i VGA 00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller [8086:2a42] (rev 07) xorg-x11-drv-intel-2.20.8-1.fc17.x86_64 xorg-x11-server-Xorg-1.12.3-2.fc17.x86_64 How reproducible: Steps to Reproduce: 1. Obtain F17 on t400 2. Work on the system 3. leave it turned on for at least 24 hours Actual results: similar results as on attached screenshots Expected results: no artefacts (white pixmaps, invisible fonts) should appear Additional info: When I did few screenshots via (gnome-screenshot utitlity) problems went away at least for now. Otherwise yes it happenes always after multiple hours of usage and I have to reboot machine to get rid of it.

Do you see this if you disable swapping?
Let me check this. I'll disable swapping and leave laptop powered on during weekend. So let's hope I'll have some results on Monday.

For what it matters, I've also started seeing similar artefacts on my fully updated F16 in the last few days. The controller in my laptop is 00:02.0 VGA compatible controller [0300]: Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 02)
I've tested kernel-3.6.5-2.fc16 (from updates-testing) and it solves at least my problems so I'm closing this Bug as a dup of Bug 852210. Please feel free to re-open if you're experience differs (-: *** This bug has been marked as a duplicate of bug 852210 ***
