Betreff: Overexposed desktop

hello, for whatever reason, the next time I've booted up, my desktop became=
 completley black. I mean, the graphical login was visible, the black scree=
n was happening after logging in.
I tried different desktops, that were installed: Gnome 3, Unity, LXDE, Xfce=
, but i was always getting black screen. I don't know, why it happened. Pos=
sibly, something got updated and it caused this problem.
It happened about a 2 months ago. After spending a couple of days troublesh=
ooting it, nothing helped, so I desided to do the unthinkable, upgrade my L=
TS 22.04 Ubuntu to the latest version, that was at the time 23.04. It fixed=
 the black screen, but the picture became overexposed:

I tried to install drivers from different unofficial repositories, but none=
 of them changed the situation, so I returned the drivers from the official=
 repository.
I tried using xrandr and other utilities to change contrast, brightness and=
 gamma with using reference pictures for adjusting those values, but it did=
n't help. White range was still cut off after certain value, but it just be=
came more dimm, when I tried to lower those values and lower range of black=
s was cut off on the lower range even when trying to raise those values.
The only time, when picture became normal was, when I loaded LXDE and openb=

Gnome 3, Unity and Xfce were openexposed.
I tried to do: openbox --replace after loading different DE, but it didn't =
work with Gnome 3 and Unity, but it worked on Xfce. Also, metacity --replac=
e works on Xfce, but, even though, it mostly looks normal on Xfce, some pro=
grams still are overexposed.
I think, the programs, that have modern interfaces. Some pdf/fb2/epub reade=
rs, Blender, mpv, GoDot, etc, Ubuntu's Software store are still overexposed=
 even in xfce or lxde with openbox or metacity.

I've noticed one thing, when loading the Desktop Environment:
On login screen the picture is normal, not overexposed.
Then, after entering username/password, the desktop starts loading normal (=
not overexposed).
Then, a few seconds after login screen disappears, while still seeing a wal=
l paper, over desktops, seems like some transparent rectangle gets loaded t=
aking almost an entire screen, not reaching edges only about 1 centimeter a=
round it and under it's transparency, the wallpaper gets overexposed, then =
shortly after the whole screen gets overexposed.

I tried to disable all the programs, that autostart, but none of them cause=
 it.
Maybe there is something gets loaded by system, that causes it.
