"failed to load content" with flycast

Hi. I’m trying to run Dreamcast games on my Moto G5 Plus with Android 8.1.0. However, always I try to load any game with flycast/reicast I get a “failed to load content” error.

Here’s a log file: https://pastebin.com/sstAKPwK

Ok, I managed to find it out. The problem was with the “screen orientation” option at video settings. For some unknown reason, the game won’t load if I select 90º option in screen orientation. Getting it back to “default” solves the problem and successfully load the game. Sounds like a bug?
