I have the same issue on a Dell OptiPlex system that originally came with Ubuntu 20.04. It ran fine under 22.04, but shows the issues described since I upgraded to 24.04.
I can confirm that some Gnome applications and Firefox seems to be affected. Gnome terminal in particular freezes each time a new window is opened. Firefox freezes almost constantly, and is pretty much unusable. Gnome settings and system updater are also affected. A bunch of third- party applications like QtCreator, RStudio, Zotero, Google Chrome etc. seem unaffected. I am running on X11 since as far as I know, Gnome still forces X11 applications to be scaled on HighDPI displays when running on XWayland. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2081281 Title: gnome terminal and other apps freezes for about 30 seconds To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gtk+3.0/+bug/2081281/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
