Is this all you see in the Emacs frame? It looks like a part of a
frame, did you clip the image, perhaps? If so, please show all of the

It sounds like Emacs is hung or infloops somewhere. Does it eat CPU
cycles? Can you exit it with "C-x C-c" or do you have to kill it by a
signal? Can you attach GDB to it (on the GNU/Linux side) and show a C
backtrace? Please do this several times, restarting Emacs each time,
to make sure the backtrace points to the same place.

To make sure this is related to GTK, could you try building with a
different toolkit, just to see if that build starts as expected?

These don't look related to me, because the problems they describe
existed before Emacs 25, which you say worked OK for you.
