It sounds like the most problematic apps are going through Xwayland. Actually I've seen similar issues with poor scaling of Xwayland apps and need to make some time to find out what the mechanism is that makes them scale correctly on Xorg but not on Xwayland...
In the meantime, Firefox should be fixable by adding a new line to /etc/environment: MOZ_ENABLE_WAYLAND=1 and then reboot. Chrome support is coming, but I've read isn't quite ready yet: https://www.phoronix.com/scan.php?page=news_item&px=Wayland-Chromium-2020 https://wiki.archlinux.org/index.php/chromium#Native_Wayland_support Although native Wayland support is all longer term. In the shorter term I wonder if we can fix Xwayland/mutter to communicate the correct scaling factor. ** Tags added: multimonitor ** Tags added: scaling ** Also affects: xorg-server (Ubuntu) Importance: Undecided Status: New ** Summary changed: - multiple monitors with mixed DPI not scaling correctly + Multiple monitors with mixed DPI not scaling Xwayland apps correctly ** Tags added: wayland -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1913681 Title: Multiple monitors with mixed DPI not scaling Xwayland apps correctly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1913681/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
