Ok. I removed the libva patch completely. I wasn't really happy with this patch in the first place, but the submitter indicated that it wouldn't do any harm and that he tested, etc. Unfortunately it seems that this might be true on Tumbleweed, but for the older builds this is definitely not the case. Also I know already that future chromium builds will no longer build with this patch, so it was just a matter of time before it got disabled. As soon as the build in network:chromium is finished, I will push it out as a maintenance update.
