After upgrade video not smooth

I had a stable Celeron NUC Sandybridge version of the Intel Processor/Chipset running Kodi 16 with the Mythtv PVR addon. I’m running Xubuntu 16.04.

Everything worked fine, but a recent update put me on Kodi 17 before I was ready. I’ve noticed that any motion in a video playback is not smooth anymore. If I use the Mythtv-frontend to play the same video/recorded TV it works fine. The video settings seem to recognize that I have Video Hardware and that it is turned on.

Not sure where to go from here other than to figure out how to downgrade to Kodi 16.

Any advice?
