Without opening the machine, I ran a single pass of memtest86+, which takes about 80 minutes, no errors. I'm reluctant to do surgery on this desktop right now as long as it's my primary. When I get a new desktop and this one becomes secondary, it'll be a lot easier since it'll be off almost all the time. I'm fairly sure I opened it up sometime in the last year and would have blown out any dust which there was not a lot of.
I strongly suspect some software issue since I only see the corruption either in the top panel or in the two specific applications MyPasswordSafe (a very old password manager, I'll have to migrate eventually) and hexchat, which I stopped running since there's very little activity on IRC nowadays. Since those two applications are very old, they might be misbehaving somehow. When I brought up MyPasswordSafe and saw the dmesg error above, the MyPasswordSafe window had been corrupted immediately when it started, so I suspect those are connected. Usually it's either not corrupted or it happens gradually. I suspect bringing up MyPasswordSafe triggered the GPU hang. -- _______________________________________________ users mailing list -- [email protected] To unsubscribe send an email to [email protected] Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/[email protected] Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
