The plan is to just continue monitoring crash reports. Still, we are confident this is the fix because: * The offending source code in libx11 tells us it is :) and * The crash only started in Ubuntu with gnome-shell 3.34, which is the exact release in which XInitThreads was removed from mutter. [Regression Potential] Low. We add a single function call that tells libX11 to enable thread safety. This same function call as one we had in bionic, cosmic and disco.
