I upgraded from 23.10 to 24.04 only yesterday and my Nautilus has always been generating thumbnails for me perfectly fine, but I've been having broken thumbnails in the Gnome Settings app - on the panel for changing the wallpaper. And, yes, it were the wallpaper thumbnails that were broken.
The point is that all of that was also resulting in hundreds of files being generated under ~/.cache/thumbnails/fail - even if I kept on deleting that directory. What ended up helping me is adding to /etc/environment the line: GSK_RENDERER=gl Then either restart or execute: sudo systemctl restart gdm.service After I did that, the wallpaper thumbnails appeared fine in the Gnome Settings app and it magically fixed another rendering issue that I've been experiencing. The directory ~/.cache/thumbnails/fail kept reappearing, but now, instead of constantly re-creating hundreds of files in it, only a single file is being re-created. Weird. But I suppose, in this case, one is hundreds of times better than hundreds. 😂 Perhaps this would help others as a work-around - or as a hint toward fix this one. Apparently this fix has helped a lot of people to solve a lot of similar issues: https://askubuntu.com/questions/1511575/ubuntu-24-04-screen-glitches-on-gnome-apps-after-install https://askubuntu.com/questions/1511856/24-04-lts-texts-dont-appear-until-hover https://askubuntu.com/questions/1515056/missing-text-in-dialog-windows Further info and discussion: https://www.reddit.com/r/gnome/comments/1bnjx22/gnome_apps_do_not_show_text_unless_fullscreen/ -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/2047256 Title: Ubuntu 24.04 Some image thumbnails no longer displayed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/2047256/+subscriptions -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
