It also crashes for me. Radeon RX 7800 XT, sddm, kernel both 7.2.6 and
7.2.10, firmware-amd-graphics both 20260810-1 and 20260916-1, everything
else from current sid. Rolling back xserver-xorg-core and xserver-common
to 2:21.1.24-1 fixes it.
One crash, with my usual weird xrandr --scale setup:
(II) AMDGPU(0): Allocate new frame buffer 7680x2160

(sorry, not going to install debug symbols and do all of this again)
would you be able to bisect it? There are only 44 commits in this
release, mostly CVE-fixes..
