   Indeed, and you also tried to tear a chunk out of Pjotr :-)   
   Did you notice Pjotr's post count ? Posts: 21427   
   What's your post count ?            Posts: 128   
      
   This is what I can contribute. This seems to get forked when   
   you use the help menu in GParted. I was hoping this "thing"   
   would be a simple piece of software, but it is a bottomless   
   pit of trouble. If there is a font call in there, I'm going   
   to need a research team with an electron microscope to find it :-)   
   This is not some Saturday afternoon noob programming project.   
   It's behavior is similar to a malware, in fact. Yelp is   
   searching things, and looking places, it shouldn't be looking.   
      
   $ strace /usr/bin/yelp help:gparted   
      
   That's not exactly gparted code to start with.   
      
   You are starting some sort of agent which understands   
   HTML documents perhaps. It seems to want to open some sort   
   of rendering path. There are a metric ton of unfound files,   
   as it tries to figure out whether you're X or Wayland or   
   MESA or DRI or Nouveau or... well, it's diet is so extensive   
   it almost looks like malware. It likely knows your shoe size by now.   
      
   Only one problem. Whatever "surface" it was supposed to open and   
   display, just isn't happening on my setup ("blackness" the result).   
   Remember, this is the disk I did the clone experiment with, and   
   it has LM221 on it. I seem to have reproduced enough of your problem,   
   and it would appear "yelp" just doesn't grok where it is   
   and what it is doing. So far in the strace, I don't even   
   see it remotely locating the help for gparted. It's just   
   farting around reading every subsystem the computer has got.   
      
   "WebKitWebProcess"  <=== seems to be forked and not in my strace   
                            output because it is a separate process   
      
   The fonts in that surface, would be rendered by WebKitWebProcess.   
      
   I am on Linux Mint 221 Xia Cinnamon.   
      
   *******   
      
   It would seem the console messages displayed after executing "sudo gparted"   
   have meaning after all. At least, that gets me a hit in a bug filing.   
      
   https://bugs.launchpad.net/ubuntu/+source/yelp/+bug/1969015   
      
      "for my understanding this leads to unreadable text when using a non-dark   
   theme"   
      
      "The bug has been fixed in mantic.   <=== Yes, and my mom wears army boots   
       Thanks!   
      "   
      
   I already tried the theme idea and that did not help.   
      
   My LMDE6 DVD live session is using the same theme, it sprouts   
   the same feedback ("recursion depth"...), yet LMDE 6 Yelp, works.   
   It's also a Cinnamon, running Nouveau, just like the   
   other (failing) setup LM221 Cinn. the factor causing the darkness   
   then, is .

   That is all the progress so far. Since I can reproduce your   
   problem, just by running Cinnamon, and without deleting   
   fonts, this is some bug we've found. You can see in the picture,   
   what it would have looked like, if the rendering surface   
   had actually worked. When it fails, the rendering surface is   
   dark, when the rendering surface is working, the surface is   
   white (on a "mixed" theme setting), and the white surface   
   should appear even if the fonts were borked. It's almost   
   like an OpenGL call isn't working.
