I'm having similar problems on Kubuntu 9.04 x86_64 KDE4 on Thinkpad T400 (internal Intel MGA) with 512Mb internal and 1Gb additional ram shared with the adapter. Corruption appears when desktop effects have been turned off while changing between windows, and disappears when the corrupted window contents are redrawn (i.e. opening menus, scrolling, resizing). This is a fresh 9.04 install. I have ran multiple passes of memtest86+ to ensure there is no corruption caused by faulty hw.
I'm attaching lspci -vvnn, xorg.conf and a screenshot demonstrating the problem. Unlike in the screenshot above, it's not restricted to text only. Interestingly the corruption is only restricted to qt apps (no corruption ever in Firefox, Gimp or other gtk apps), but I'm posting this comment here in case it might be related to the driver as well. ** Attachment added: "Blurred parts are not part of the corruption." http://launchpadlibrarian.net/26390160/corruption.png -- [Q45] Display corruption on Intel chipset https://bugs.launchpad.net/bugs/362919 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs -- universe-bugs mailing list universe-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/universe-bugs
