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 Thread 1 "perl" received signal SIGSEGV, Segmentation fault. 0x00007fff00000001 in ??
