[3dprinter-general] Bug#915347: slic3r segfaulting under wayland

[Bernhard Übelacker]

Dear Maintainer,
this issue seems to be caused by wxGLCanvas not being yet ready
for wayland. At least in version current version in testing.

There are already bugs [1] and [2], the first one also for slic3r.
Both are forwarded to [3].
And all describing as workaround using something like
"GDK_BACKEND=x11 slic3r" to start affected applications.

[1] https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=900678
[2] https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=904753
[3] https://trac.wxwidgets.org/ticket/17702

Kind regards,
Bernhard
