That doesn't show a memory leak.
Indeed, but we're talking about 3GB of memory here, which seems hard to
justify for such an application.
awk '/Name|VmSize|VmPeak/' /proc/$(pidof gnome-shell)/status
Name: gnome-shell
VmPeak: 1250636 kB
VmSize: 1190912 kB
More than 1GB also sounds excessive, so you seem to be suffering from
the same problem.
Of course, maybe this is not a problem, it is just an artifact of
gnome-shell sharing a lot of memory with other applications, so it's not
actually eating up all your RAM. But this explanation seems unlikely.
I think it deserves a bug report.
