None of these seem to help fixing the problem, so I don't really know
what to do. The only thing that comes to mind is to try to set max bpc
to really low numbers to check if that is what causing the problem. Is
there a way to get the current value of this variable via terminal?

You can find more amd64 debs in:
https://kernel.ubuntu.com/mainline/v6.8.12/amd64/
https://kernel.ubuntu.com/mainline/v6.9.3/amd64/
And yes you can force a lower bandwidth signal with something as simple
as:
xrandr --output DVI-D-0 --set 'max bpc' 8

Well, it did not work. I heard that 6.8.9 should work, but there are no
.deb files in the repository for amd64, so I'm not sure how do I install

Also, you said about different color schemes, is there a way to use a
lower-bit one? In case that causes the problem.

Display cables matter a lot because they have to transmit gigabits per
second and small imperfections can interrupt that randomly, leading to a
temporarily black screen.
The reason a cable might work on Windows but not Linux could be slightly
different signalling, if for example Windows is using 2
But why would the cable be the reason if it works properly on windows?
And I would like to change kernel if it fixes the problem, the thing is I'm
kind of new to Linux so I don't get a lot of Linux related stuff, but I already
can install packages and do other simple actions.

Since it involves installing a lot of packages repeatedly and you don't

All kernels available in the repository (not really sure which though,
that's what said in the guide at least) are 6.8.0.31 and 6.8.0.35 and
both of them have this problem. Probably there is a way to install other
kernels, though I'm unsure which version should I install, how do I do
that and does
Thanks. The only message I can see that might be related is:
kernel: amdgpu :03:00.0: amdgpu: Disabling VM faults because of

which some googling suggests is caused by the GPU being under load.
Certainly Steam was running at the time.
It might pay to try some older and newer ke
