            Bug ID: 110140
           Summary: Green bottom half of video frame when using JPEG
                    acceleration (vcn_v1_0_jpeg_ring_emit_fence() WARNING)
           Product: Mesa
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org

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

When using Chromium and HTML5 based video chat:
https://meet.jit.si/amdtest
I see image from my webcam corrupted (bottom half is all green).

It only happens with Chromium's setting "Use hardware acceleration when
available" enabled which appears to involve some JPEG hardware acceleration.

With above web chat page opened I see about 10 kernel WARNINGs per second:
