I bought a Panasonic DP-UB820P-K in January 2022. I recently noticed I get weird playback glitches when using Dolby Vision. My TV and HDMI cables are Dolby Vision compatible. Streaming Dolby Vision on the Panasonic is fine. But UHD playback with Dolby Vision causes white flashes/pixels on the far left edge of my screen even during menus and startup. Turn off Dolby Vision and its fine. I’ve seen this so far on Raiders of the Lost Ark, The Last Crusade, Kingdom of the Crystal Skull, Godzilla vs. Kong, and The Wizard of Oz. Panasonic tech support says it’s my machine that’s faulty, which seems odd. The firmware is up to date. I’ve tried resetting and reinstalling the firmware. Has anyone else encountered this problem?
