I discovered new issue, maybe it is related with what JohnWayne111 is suffering.

Easy to reproduce:
- I play netflix at 1080 with hyperion active. OK
- I activate subtitles, then image goes crazy&black every few seconds, to test it, I simply pause the video and everything is going so crazy (00:15:00).
- I deactivate hyperion, it works ok (00:30:00), I re-activate hyperion, it goes crazy (00:37:00).
- I deactivate subtitles, resume playing in order to disappear previous onscreen subtitles then I pause again. Everyting is OK (00:49:00).
So, my conclusion: something is wrong with subtitles and overlay UI graphics (without subtitles, some crazy flashes can be seen when appearing player interface when pausing or subtitles activation/deactivation notification e.g.00:07:00).
EDIT: this is happening ONLY whithout external grabber, just with hyperion getting kodi's video signal. If I force to use the signal from the external video grabber by switching priorities in config json file, everything works OK.
