Using the latest appimage on Debian, sometimes I see a double image on each button, (streamdeck+) or horizonal lines through each image. Strange burn in is there, even when switching pages some ghost images remain. Unplugged streamdeck+ for 5 minutes, ran opendeck 2.8.0 appimage again and all seems normal. Happened after adding the deck brightness rotational dial plugin and having the brigness up fairly high for a few hours.
