Wow, that did it. Thanks! Sorry about the playback screwup - I changed the launch script and then neglected to restart the frontend. Duh!

How do you know the fragment guys are too slow? You're obviously correct but when I run intel's intel_gpu_top utility it seems to say the various units are working at ~ 20% of capacity. Also, the "ring" is 60% idle, whatever that means. Even without the nofrag it was similar.

Anyway, having the OSD render at the display's native resolution is beautiful. I'll give it a rigorous shakedown over the next few days but so far it's looking good. Thank you!
