With some recent update, when a video is playing, the screensaver starts in the background while it is being played. Once you do something like select another audio track in the video, the screensaver goes full screen and you have to press a button to first disable it and then see what you’re choosing. Same happens if you select to fast forward to a next video in the folder - first you will see a screenshot appearing from background. This behavior was not there before some of the updates (not sure which one of them).
