Subject: 5.2: display corruption on X60, X220

Hi!

In recent kernels (5.2.0-rc1-next-20190522, 5.2-rc2) I'm getting
display corruption in X. Usually in terminals, but also in title bars
etc. Black areas with white lines in them, usually...

Same configuration worked properly in ... probably 4.19? Then I got
some graphics-crashes on X220 that prevented me from testing :-(.

It's pretty hard to say anything based on the above.

Anything in the logs with drm.debug=14 added?

BR,
Jani.

I see. It looks like hard-to-debug issue.

Oh, interesting part is that corruption _is_ visible if I make a
screenshot.

Will try with drm.debug=...

Do you do some kind of testing that would catch similar issues?

Thanks,
Pavel
