Why do you believe the monitor runs in 1922x1200 mode? I can't find any proof for this claim in any logfile or output you've provided.

As I understand it, the monitor reports 1922x1200: (In reply to Stanislav Brabec from comment #2)

But the display OSD shows that, and it causes visual artifacts.

But it seems that every component things that 1920x1200 is used. Probably only the vc4 driver or the GPU itself fails to set it correctly. You wrote that you upgraded to 42.3. Can you try to boot with kernel from 42.2 and with kernel from Tumbleweed? I think experimenting with different kernels is the easiest way to narrow down what and where may be broken. -- You are receiving this mail because: You are on the CC list for the bug.

Debian kernel from NOOBS 2.4.0 is not affected. I will try other kernels. -- You are receiving this mail because: You are on the CC list for the bug.

So we know which one of 4.4 and 4.0 kernel DRM is affected. Or both ... -- You are receiving this mail because: You are on the CC list for the bug.
