Page reload during playback after each track + resolution issue

I’m running Audirvana Mac Version 3.5.15 (3545)
on macOS 10.14.5 with 8192MB RAM.

When I open my library and click on an album to play, everything works as expected.
After each song though, the entire page reloads (all album covers are gone for a second or so) and then everything comes back and continues playing the next track.
After a few times, the resolution or size of the screen is changed. I now have 7 albums in a row instead of 6 but the last column is mostly off the screen.
It seems Aurdivana thinks that my screen is wider than it is.
When I go to ‘full screen’ mode, everything shows up correctly again for a while but it will eventually become the same again.
Anyone with the same problem? Any fixes for this?
