Critical bug on Fedora 30 / Ubuntu 18.04 when using Wayland

Hello everyone,

Inkscape 1.0a isn't usable at all for me at the moment on Linux when 
running it under Wayland; it appears to be missing most of the mouse 
events or something. I cannot draw even the simplest geometry! I haven't 
figured out how to make a screencast that shows the mousepointer, but 
maybe that's another Wayland issue ;-). Can't show it to you because of 
this, but it's really bad.

I don't recall any reports about this and cannot find anything in the 
Gitlab issues either, but surely others must be experiencing this too... 
Unless everyone else is still on Xorg. I've reproduced this on both 
Fedora 30, with current trunk, as well as on Ubuntu Gnome 18.04.2, using 
the inkscape-trunk PPA. When I use Xorg, the problem disappears, on both 
distros. This is rather problematic though, because all (?) linux 
distros that have gnome also have Wayland enabled by default these days.

Any pointers? A bug report maybe? Otherwise I will file one myself, and 
start some debugging.

Best regards,

Diederik
