I've also run into this issue on Pop!_OS 20.04 LTS; Nvidia driver 450.66; Linux kernel 5.4.0-7642-generic; GeForce GTX 1080 8GB; mutter 3.36.4; GNOME Shell 3.36.4.
I'm running two monitors: NS-PMG278 (144Hz DP connection) + Dell U2719D (60Hz DP connection), both at 1440x2560.
I'm getting the exact same symptoms as seppel. Updating /etc/environment with __GL_SYNC_DISPLAY_DEVICE doesn't seem to help either.
