@Markswift2003 . I was playing an episode of Handmaids Tale, via a MKV file. A friend pointed out I have a series of dead pixels top left of the screen. I recognised it as a file problem rather than a string of dead pixels. It actually looked like an old 2” VTR tearing. Anyway I stopped playback and rebooted and problem went away. Earlier before rebooting I check a few other files and couldn’t repeat the error. I checked the Handmaids file with MKV validator and it was clean so I can only surmise it was a cache/memory/? problem with the Zidoo. At the time I wasn’t in a position to take a photo mores the pity. If only there was a simple access to a zidoo log file? a mystery
