Device: MECOOL BB2-PRO (S912 - 3GB RAM - Gbit Network)
Release: 188.8.131.52 by kszaq
Scenario: When playing 4K content, or when setting the UI to 4k resolution, i get a split screen with the top and bottom half of the screen showing the same mirrored image. In the Log, my UI is set to 1080p at 60Hz. Once i start playback of the 4K movie (Alien Covenant) i see the splitscreen, with UI in foreground and movie in the background on both halfs.
Since i also couldt get the 720p resolution switching (mentioned in the release notes) to work i also played a 720p movie (Primer). Again, UI is set to 1080p at 60HZ. when i start playback my TV is getting a 1080 at 24Hz signal, instead of 720p at 24 Hz.
