I don't know about the HiDPI deamon. It's not my picture. I did however experience the same problem.
The software used is a regular ubuntu 19.04 with the default window manager. At the moment I can't connect the monitor. I'll try to get a journalctl log after experiencing the issue when I do use the monitor again. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1852864 Title: Fractional Scaling shows a black bar To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1852864/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
