I have now played a fair bit with my game and I have not had any crash 
so far.

But, instead, there are rendering glitches at times. Of course I suppose 
that these glitches occurs whenever the plugin would have crashed 
previously.

It's no big deal, but it shows that indeed, as you stated, some 
continuation is needed when "the edge is not on top" to "toggle its 
(back) fills", whatever that means.

Best,
