I'm experiencing a drop in sound quality when the Spotify window is not the one I am actively using--that is, if it is minimized or if I am working in another window (Windows 10, plenty of resources available on task mgr). I tried to disable hardware acceleration and this was not the problem. I still get acceptable sound quality (premium user) but when I have that window active, the quality is much higher. If I change to another window, I can hear the sound quality decrease. This is happening fo songs I have downloaded, so I don't think it's a streaming problem. I wasn't able to find another discussion about this so if anyone has a fix or explanation that would be great!
