Same here on Linux Mint 19.3 Xfce 64bit (Ubuntu 18.04 LTS), Spotify version 126.96.36.1991.gbe11e53b. The player freezes but I still can interact with that (keyboard, mouse - while figuring out where the itens are) and even the window title displays the song. If I switch windows or keep trying to use the interface it gets a white screen, but still responding to my commands. I couldn't figure out when exactly it happens (e.g. time or usage) but, the more I use it the more it happens. I'm a heavy user, it's really annoying me.
Another Fedora user. Sometimes I get a blank screen when I open it that doesn't go away. Different combinations of -? and --disable-gpu flags seem to change this (I don't think the -? actually does anything except maybe clear some cache based on process name?)
The "drag the song name" thing mentioned earlier works intermittently. The player controls in the KDE taskbar work, as do the media controls on my keyboard.
I had installed it through Discover software center, which I think pulls from Snap, but I uninstalled it and reinstalled it using the snap command. I tried unbinding the OpenGL interface in Snap, didn't see any changes.
What's odd is that I ran this on Arch for months with no issues, and I'm pretty sure that was installed from Snap too. Regardless it was the same hardware.
