Ubuntu MATE 22.04 onwards use the Metacity theme from upstream Yaru, which I maintain.
I have tried reproducing this issue and can only do so in one scenario: - In the Live Session while using the nouveau driver for NVIDIA GPUs. @Simon Morgan: Please provide more details about your iGPU/dGPU and drivers. ## Work around - Press Alt+F2 - Run: marco --replace Or, use MATE Tweak to set the DPI to HiDPI. ** Changed in: ubuntu-mate-artwork (Ubuntu) Status: New => Invalid ** Changed in: yaru-theme (Ubuntu) Status: New => Triaged ** Changed in: yaru-theme (Ubuntu) Importance: Undecided => Low -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1967507 Title: Yaru Metacity theme has incorrectly scaled windows buttons on HiDPI displays To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/marco/+bug/1967507/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
