Hi,

I am using MythTV 0.31 on Gentoo Linux with Nvidia driver 390.138.

After upgrading MythTV to 0.31 and also some other stuff, VDPAU is not
working anymore and I get lots of buffering and slow playback.

My playback profile is looking good.

vdpauinfo looks good and also glxinfo.

When starting mythfrontend, I see:
