I'm not sure Xorg sessions are meant to support different scaling factors per display. Because Xorg forces all compositors to render all monitors from the same framebuffer. So presumably all displays are stuck with the same scaling factor. This is fixed in Wayland sessions, but Nvidia has too many bugs on Wayland in 24.04, which is only fixed in 24.10 and later.
Because of all this, and the fact that we expect Xorg sessions to be removed completely in 25.10, this bug is a "Won't fix" for future Ubuntu. But there's a small chance it's fixable for 24.04 Xorg sessions. The artifacts you mention sound like bug 1924689. ** Summary changed: - Wrong font scaling with multiple displays + Wrong fractional scaling with multiple displays on Xorg ** Changed in: mutter (Ubuntu) Status: New => Won't Fix ** Also affects: mutter (Ubuntu Noble) Importance: Undecided Status: New ** Also affects: mutter (Ubuntu Plucky) Importance: Undecided Status: New ** Also affects: mutter (Ubuntu Questing) Importance: Undecided Status: Won't Fix ** Also affects: mutter (Ubuntu Oracular) Importance: Undecided Status: New ** Changed in: mutter (Ubuntu Oracular) Status: New => Won't Fix -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2113859 Title: Wrong fractional scaling with multiple displays on Xorg To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2113859/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
