Are You sure the black screen isn't present before changing the refresh rate? Because, currently, it is supposed to create two "windows" for fullscreen games/programs and render to the 2nd one while the first window is simply black. It puts the 2nd window to the foreground, so normally this should not be noticed.
Indeed. Just checked for few other games. Black window appears without changing refresh rate.
Its so weird and annoying. Gnome-shell constantly sends notifications that black window hangs and asks to kill it. Pretty much every game is affected.
