            Bug ID: 109554
           Summary: Regression: short time display corruption during
                    resume
           Product: DRI
           Version: XOrg git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: zajec5@gmail.com

I use HP EliteBook 745 G5 with Ryzen 5 PRO 2500U.

Starting with the:
commit 009d9ed6c4b7b84dbff8314d74233da9237a4560

During most resumes from RAM I see a display with black screen & some
corruptions for a 1 second or less.

This is *not* critical but since it's a tracked regression I decided to report
it with a hope it's something easy & possible to fix. After that second (or
less) displays shows an expected image (KDE lock screen) and everything works
normal afterwards.

This problem still exists in the 5.0.0-rc3.
