I followed the instructions
https://snapcraft.io/install/solvespace/manjaro#install
When I start I get an error
Gtk-Message: 16:29:12.584: Failed to load module "xapp-gtk3-module"

(solvespace:6876): Gdk-ERROR **: 16:29:12.790: The program 'solvespace' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc'.
(Details: serial 392 error_code 11 request_code 149 (unknown) minor_code 2)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the GDK_SYNCHRONIZE environment
variable to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
