3.37.91, Wayland, Multi Monitor: Fullscreen OpenGL VSync has strange behaviour
Gnome Shell + Mutter 3.37.91
Wayland
2x 60 Hz 4K displays (different brands)
AMD Radeon Fury with RADV and Mesa from git.
Various OpenGL games, like for example Jupiter Hell has the following behviour: If I syncs to vblank and I enable my second monitor it runs at 120 Hz instead of 60.
These things do not happen if I go back to Mutter 3.36.
