I'm using LibreELEC 9.2.3 on a RaspberryPi 4. When a video is playing and I choose "Add bookmark", it produces only a "black" picture at the timestamp without any visual content.
(However, running the same LE version on a RaspberryPi 3B, adding bookmarks produces proper pictures with content at the timestamp.)
Please fix this bug on RB4, thank you in advance!
