Patch that reverts the 15% reduction in set dispclk
While I can't reproduce your issue under a similar setup I think I have an idea
of what the issue is.
Can you try this patch?

Do you mind testing another patch?
This patch has a narrower impact than the previous one (since it should only
target Vega). I imagine that it would also fix your issue but it'd be nice to
have verification.

--- Comment #5 from Dave Johnson (dave@locochino.com) ---
This is possibly related to my issue that popped up in 4.18, Vega 64 works with
one of my displayPort monitors but not the DVI. from what I've seen others
reporting on various searches on my issue, it's something with a clock setting
where a khz value is referenced as "10" instead of "1" or something like that.
Vague, I know, but I dunno.
Some get black screen, I get one display but not multi, and the user above me
has corruption.

I think you're referencing this patch:
https://patchwork.freedesktop.org/patch/238065/
Which should be fixed in 4.18.
Please post a new ticket with a full dmesg log, Xorg log and your
distro/desktop environment if you can still reproduce the problem.

Ok, so yes and no I guess. I was assuming a single bug while there are
apparently two. The one that causes video corruption and artifacts is in fact
fixed for me now, but the multi-head support is still broken. It worked a
couple of kernels ago, opening a new bug report over at opensuse since it seems
to be opensuse specific for some reason (other live CDs work fine, looks like
it's just something with Tumbleweed for whatever reason)

Update: for my possibly-separate-issue I can confirm that multi-head works on
4.16.13 and not 4.19_RC3
For now I'm staying on 4.16 as it's working perfectly back there.

I get the same visual corruption as well. It only appears when I run the
monitor at 144Hz. 120Hz seems fine.

Will this patch be backported to 4.19? Seems like right now its only in 4.20.

This was fixed for both Vega and Polaris but I think there was another
regression that only affected Polaris in that release.
It should be fixed in amd-staging-drm-next. It'll probably make its way into
stable at some point.
