Thanks for the YouTube video, but the resolution is unfortunately too low to show the issue; *everything* looks blurry there so I can't tell what's worse.

Some questions:
1. Is this with the Wayland session, or the X11 session?
2. What scale factors are these screens using?
3. Does it affect all apps, or only Chromium? How about apps you know are running in native Wayland mode like Dolphin?
4. If Chromium is running in XWayland mode, does it help if you force it into native Wayland mode using the instructions at https://wiki.archlinux.org/title/Chromium#Native_Wayland_support ?

Comment 3 Chris H. 2025-07-12 15:31:08 UTC

1. yes, Wayland session.
2. All the scale factors are set to 100% between all of the monitors
3. tried dolphin doesn't bug out, only does it in chromium so far.
4. currently a new linux user (trying to figure out how to do this step)
