JoshStrobl I sort of got ghosted in reporting that bug. It's really a pity because as a technical user I am a good resource in providing information. For example, I could provide a backtrace with GDB (they closed with "missing trace"). Also, not nice that they say "why does Solus ship with this buggy thing we won't do anything likely the problem is there". I hate this sort of attitude...
Anyway, I've simply switched to VA-API and have had no more problems. Thank you Josh for removing VDPAU to make it easier for others.
