In my case, appending __GL_SYNC_DISPLAY_DEVICE=DP-0 in the /etc/environment file (DP-0 is my 144hz monitor - see X Server XVideo Settings in NVIDIA X Server Settings) seems to works (config: GTX 1070/60 Hz + 144 Hz monitors).
I forced resolution + frequency in NVIDIA X Server Settings for the two monitors in the X Server Display Configuration section.
Disabled Force Composition Pipeline + Force Full Composition Pipeline.
Disabled Sync to VBlank + Allow Flipping (OpenGL Settings).
NVIDIA driver version: 435.21 (the latest in Ubuntu 18.04.3 with HWE enabled).
