Package: chromium
Version: 47.0.2526.16-1
Severity: important

Dear Maintainer,

I tried to install chromium 47 from experimental, but I found out that
it completely breaks the GPU accelleration. This might have something to
do with this entry in the Debian ChangeLog:

* Enable accelerated video decoding (closes: #793815).

I noticed the issue because chromium got very slow. In chrome://gpu the
Graphics Feature Status flags are all bad (see attachment), while they're fine
in chromium 46. I also get this output from chromium 47 that I don't get
with chromium 46:

Downgrating to chromium 46 solves the issue.
I hope this can be fixed before chromium 47 hits Sid.

Thank you,
