As you action things (use a menu, click on a different window etc) the black fragments move (though often only parts of screen; not all of screen) ** Background This was looked into because of a number of support requests and I detected a pattern. All users are using the HWE kernel, and issue didn't occur using 18.04.4, though I personally only tested the live daily (during the development cycle). - thinkpad x31 https://discourse.lubuntu.me/t/reviving-thinkpad-x31-problems-with-messed-up-screen/1457/ - thinkpad t42 https://ubuntuforums.org/showthread.php?t=2448800&p=13979514#post13979514 - thinkpad t41 https://askubuntu.com/questions/1266918/latest-updates-to-lubuntu-18-04-4-lts-32-bit-create-almost-impossible-graphics-i (and I believe others before I recognized the pattern & started noting; I ignored initially as I had no issues with t43, not having used the t42p or r50p in QA testing for awhile - a scan of my QA- testing live will show when I tested with each box in first line of comments). I've also seen this on very different boxes to old thinkpads too. My boxes impacted - ibm thinkpad t42p (pentium m, 2gb ram, amd/ati mobility firegl t2; rv350/m10 gl) - ibm thinkpad r50p (pentium m, 1gb ram, amd/ati mobility firegl t2; rv350/m10 gl) ** 20.04/HWE kernel only If I live QA-test using the 18.04.4 ISO or released image, no issues occur (using 5.3 kernel & it's packages). Likewise I have no issues using the GA (4.15) kernel in testing (the r50p was used more regularly in testing in prior bionic cycles, alas not much in 18.04.5 development/recently; expecting same results with thinkpad t43 which does not have this issue) This report should possibly be filed on xserver-xorg. I've only experienced it with old radeon thinkpads (but screen on box makes it difficult to explore) (Filed online as I've been struggling to file this on actual box) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1891790/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
