Maybe do an 'strace' on the process.
I've done that, but nothing obvious is going on. However

In my fedora 31 virtual machine, the hang happens the

If I use virt-manager to tell it to emulate IvyBridge

I have this feeling there is one of those gnu-indirect
functions in the library that is busted for whatever
architecture feature it is checking for on an i9-9900K
and that indirectly screws up something in gtk2.
