This issue seems to be affecting me too, some people say it's been fixed in 18.2.3/.4 however I'm running 18.3.1 and definitely have the same symptoms in regards to Godot freezing up, I don't know much so can't be more help, there seems to be some discussion relating to the issue here though:
Are you sure that is the same bug? That one wasn't a Mesa bug it was a bug in GCC.
