I rechecked all kernels of version 4.18 again. No bug kernels only:

Thanks. If there is no bug at kernel 4.18.10, did you verify the bug is
present in 4.18.11?

[amdgpu] Flickering graphics corruption in kernel 4.18.0-13.14-generic
Ok, I consistently checked the kernels from version 10.18.20 to 10.18.10. There
is no bug at 10.18.10. If you need it later, I can check on versions from
10.18.9 to 10.18.1.
What need to provide logs on the working core?

Sounds like we _could_ make this a duplicate of bug 1802976. But I
wouldn't just yet...
If you are sure that reverting to an older kernel like 4.18.0-10 fixes
the problem then we should focus on that here.
Can you please find the *latest* older kernel version that fixes the
problem from this
I think this problem is identical to mine.

It looks like a problem with the Xorg graphics driver:
