I have a system with ubuntu 18.04 and Xibo-player installed via snap.
Xibo player only has one slide to play, which is a carousel of 5 videos in a loop. This slide plays from 8 in the morning to 8 at night.
The strange thing is that every few hours, a black stripe appears at the top of the player, dragging the video down and making it drop out the bottom. As if a margin was put on top. This worsens throughout the day, sometimes ending up with a small stripe and other times with a large one, about the size of a hand.
If I close the Xibo player and reopen it, it is correct again, but this is not a feasible solution for current system usage.
Anyone know what might be happening?
