very strange playback issue - decoding/rendering problem?

I run across this problem sometimes on videos I've pulled off the internet. I don't think a specific codec is causing it because I've seen the problem on AVI files, Youtube streams, and WMV files.

I don't even know how to explain it. The video does not launch in full screen, only in a portion of the top lefthand corner of the screen and looks terribly interlaced with strobing.

This is an old Christmas program I pulled from Youtube. No conversion has been done to the file. I can pull a codecinfo on it if thats helpful

How about a full kodi.log (debug enabled) for starters? Right now we have no idea what you are running LibreELEC on.

I have a PC built with mobile hardware and a GT430 video card.

I figured out what was going on last night. I had the PC set to output a 60hz signal, and to adjust the video output on stop and start. When I'd play something encoded at a pal rate it wouldn't switch the output - it kept spitting out 60hz.

When I adjusted the standard output to 59.94hz it started playing everything correctly.
