        <pre>[regression] Video playback is corrupt with Mesa 17.3 (but is fine with 17.2)

THESE STILL WORK:

gst-play-1.0 --videosink glimagesink bbb_sunflower_1080p_60fps_normal.mp4
gst-play-1.0 --videosink xvimagesink bbb_sunflower_1080p_60fps_normal.mp4
gst-play-1.0 --videosink ximagesink bbb_sunflower_1080p_60fps_normal.mp4

THESE DON'T WORK:

gst-play-1.0 --videosink clutterautovideosink
bbb_sunflower_1080p_60fps_normal.mp4
totem bbb_sunflower_1080p_60fps_normal.mp4

Specifically the corruption only occurs under the combination of:

Xorg +
VA-API (gstreamer1.0-vaapi) +
clutterautovideosink (libclutter-gst-3.0-0) +
Mesa 17.3.3

So that's includes the default video player (totem) in Ubuntu 18.04's default
session :(

We first noticed the regression when Ubuntu 18.04 upgraded Mesa
from: 17.2.4-0ubuntu2 (WORKING)
to: 17.3.3-0ubuntu1 (FAILS)

One workaround that works is to downgrade to these specific packages:

<a href="https://launchpad.net/ubuntu/+source/mesa/17.2.4-0ubuntu2/+build/13697262/+files/libgl1-mesa-glx_17.2.4-0ubuntu2_amd64.deb">https://launchpad.net/ubuntu/+source/mesa/17.2.4-0ubuntu2/+build/13697262/+files/libgl1-mesa-glx_17.2.4-0ubuntu2_amd64.deb</a>
<a href="https://launchpad.net/ubuntu/+source/mesa/17.2.4-0ubuntu2/+build/13697262/+files/libglapi-mesa_17.2.4-0ubuntu2_amd64.deb">https://launchpad.net/ubuntu/+source/mesa/17.2.4-0ubuntu2/+build/13697262/+files/libglapi-mesa_17.2.4-0ubuntu2_amd64.deb</a>
