Hi, i just try updating the player to the latest and the issue are the same
the first video was removed, but now the black screen issue apears more lately, i can’t recognice how many loops need to arrive there but it does 
the memory usage it’s no more than 200mb of the player, and the whole use is arround 60% of 4gb
the the odd is i have 5 devices (intel NUC5cpyh) where 3 of them have the issue, and 2 plays the 3 videos in loop without any black screen
in this moment i create another layout without the last video and i assigned to the updated device
there is a new log, without the first video
