Hi thanks for the report, this is most likely produced by the main GTK thread not handling the updating of text gracefully.

I made some changes to how threading work during rendering of messages that might do the trick

Unfortunately, in 7.5.4, this still persists on a clean install (regenerating the message seems to be the most surefire way to do it):

Gtk:ERROR:../gtk/gtktextlinedisplaycache.c:196:gtk_text_line_display_cache_take_display: assertion failed: (g_hash_table_lookup (cache->line_to_display, display->line) == NULL)

Same here. I can also get it to crash by running a model that isn't suffering from a bottleneck.

Other errors it throws when reproducing the issue include:

Gtk:ERROR:../gtk/gtktextlayout.c:2396:gtk_text_layout_create_display: code should not be reached

and

Gtk:ERROR:../gtk/gtktextview.c:6110:gtk_text_view_paint: code should not be reached

In addition to the error Ferenc and roland are getting. I'm not sure if my error messages are new or if they were happening in 7.5.2 since I kinda just followed my instinct to update first, but I figured better to weigh in with the errors I got than to assume it's unrelated.
