I ran into another X problem with 10.1 and my Radeon 5450 card. It may or may not be specific about that card: I need to do more experiments. The trigger for this issue *may* be Firefox: when playing a video on https://web.whatsapp.com/ . However the video that may have triggered the issue seems to have been removed by the sender, so it's a bit hard to retry exactly. The issue seems to be memory corruption of X's collection of (small) bitmaps. For example in ctwm titlebars, the stippled area in the middle gets corrupted. And so do all xterms. (Possibly only xterms with bitmap fonts). When it happened yesterday, most of these bitmaps (i.e. characters) got blanked out and some got some random-ish pixels in them. Repainting the windows (such as like switching workspaces) doesn't help. So it seems like the bitmaps of the font's characters get corrupted at the source. Firefox (132.0.2) itself renders itself differently and was hardly affected. Restarting my X session (from base) restored normality. This was the second time it happened and if my vague recollection is correct, the first time was also after playing some video in Firefox. Although it may have been on YouTube (I'm not 100% certain). On the other hand I played a lot of YouTube videos recently without issues. I will have to do more experiments to see if I can trigger this on different hardware (I don't care so much to experiment on my main desktop machine). So it may be a Radeon-only problem, or not. I don't think this ever happened with 9.x so it seems like a regression. -Olaf. -- ___ Olaf 'Rhialto' Seibert <rhialto/at/falu.nl> \X/ There is no AI. There is just someone else's work. --I. Rose
