Ubuntu 22.04.2 Live session dmesg output

After changing resolution (for example from 1920x1080 -> 1680x1050) from GUI
(Displays section in GNOME Control Center or KDE systemsettings) I'm getting
this ttm WARNING (dmesg).
It occurs in several distributions like:
- Ubuntu 22.04.2 (GNOME, X11) Live session, kernel: 5.19.0-32-generic (64-bit)
- openSUSE Leap 15.5 (KDE Plasma 5.27.4, X11), kernel
5.14.21-150500-55.19-default (64-bit)
- Manjaro (KDE Plasma 5.27.7, X11), kernel 6.1.49-1-MANJARO (64-bit)
- Manjaro (KDE Plasma 5.27.7, X11), kernel 6.5.0-1-MANJARO (64-bit)

It seems that changing resolution with xrandr (after reboot) does not cause
this problem.

I'm attaching dmesg output from Ubuntu 22.04.2 (GNOME, X11) Live session.
