The object was to disable Debian's disabling of internal inxi update mechanism,
and I forgot to tell you to use it as step 2:
inxi -U
Current upstream version is 3.3.27. Bullseye's is ancient, lacking, and quite
broken in inxi parlance.

Thus, expected info is missing, and too long lines wrapped.

15 or more years years ago, Xorg was reconfigured to lie about DPI and screen
size. It forces DPI to 96 regardless of actual screen dimensions, and shows the
actual physical dimensions required to produce 96 DPI. If you wish actual DPI
used, or any arbitrary DPI, it must be forced through xrandr or /etc/X11/xorg.con*.

Nothing obvious shows up in the log or your incomplete inxi output, except that
you have the exact same GPU as I have in a currently idle PC here, with TDE,
that's due for an update, so if what I suggest below doesn't help, I'll do that
this afternoon to see if it repros here.
Try using the (default) modesetting DIX display driver instead of Nouveau. Remove
package
xserver-xorg-video-nouveau
and reboot to see if it makes a difference. I use only the DIX for all of my
NVidia GPUs. It's so default it isn't separately packaged. :)
DIX: Device Independent X (display driver).
All other high competence display drivers are DDX, Device (brand/model) Dependent.
