            Bug ID: 110344
           Summary: Performance regression in mpv
           Product: Mesa
           Version: 19.0
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/i965
          Assignee: intel-3d-bugs at lists.freedesktop.org
          Reporter: fdbugs at fratti.ch
        QA Contact: intel-3d-bugs at lists.freedesktop.org

When playing back 720p50 (as in, yes, 50 FPS) content fullscreened on a 1080p
screen in mpv using the gpu-hq profile and the ewa_lanczossharp scaler, mpv
massively drops frames in Mesa 19.0, which it doesn't do with Mesa 18.3.

00:02.0 VGA compatible controller: Intel Corporation HD Graphics 620 (rev 02)

To test this:

mpv --no-config --profile=gpu-hq --scale=ewa_lanczossharp
--video-sync=display-resample --fullscreen testfile.mp4

Latest mpv from git, though it also affects the 0.29 version.

The person to fix this will be sent artisanal Swiss chocolate if so desired.
