            Bug ID: 107953
           Summary: Screen Corruption (Bisected)
           Product: DRI
           Version: DRI git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: critical
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: nick.tenney@gmail.com

After updating to a git build of the amd-staging-next branch (previous from
July), approximately the lower half of my UWQHD screen was garbled. I bisected
the issue to this commit: 5ae6fe572929587a304471bf4a641361a45152b5
drm/amd/display: Use calculated disp_clk_khz value for dce110

Let me know if anything else is needed.

Thanks for the report. This had a Vega specific fix in mind but I guess it
extends to Polaris as well.

I would imagine the first patch from this thread should fix your issue (ie. the
one that's *not* the dce120 one)

https://bugzilla.kernel.org/show_bug.cgi?id=201067

If it doesn't, then you should post your full dmesg and Xorg logs.

Thanks for the patch (and sorry for the delayed review).

The revert did the trick and works fine here.

Just curious, was this superseded by b6bb2aa2181037c9f6083aa2016e1c7e7424e0f3
in Alex's tree?
