Oh, drat, of course it should be 3.22.30 - the download folder link I 
gave is correct, but I accidentally left the ".22" out when referring to 
the actual version of GTK3 that I downloaded and patched - sorry!

My patched version of 3.22.30 did get rid of the "black window" problem, 
but also seems to have introduced an issue where it was no longer 
possible to grab the center left-right panel dividing line when using a 
toolbox in multi-window mode. Leastways going back to the 
Gentoo-installed 3.22.30 did get rid of the problem of not being able to 
grab and move the center dividing line. Bleh.

I'll give that a try -thanks! for the link.

Best,
