<pre>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.</pre>
