Potential patches that can be backported to rhel7 could be https://gitlab.gnome.org/GNOME/mutter/commit/01e20a6ba9e0 and https://gitlab.gnome.org/GNOME/mutter/commit/bf4ccd21c1be. Many others depend on non-trivial changes to frame scheduling. Created attachment 1606108 [details]

Screencast from reproducing the bug
I cannot reproduce the bug and raise the CPU load to 100% by using NVIDIA Corporation GF100GL [Quadro 4000] with driver version 390.116. I will try another graphics card and driver. Created attachment 1606865 [details]
