Projucer Segfault, Ubuntu 19.10 + JUCE 5.4.6

Hi all, new to JUCE but just trying to launch Projucer. I was able to get the login screen, logged in successfully, but now Projucer just segfaults at launch. Backtrace via gdb isn’t particulary helpful:

Is 5.4.6 on Ubuntu 19.10 working for others? Any ideas where I can begin the bughunt?

[EDIT] My bad, burned by Wayland.
GDK_BACKEND=x11 Projucer
did the trick.

Thanks,
David
