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 frame. > I can compile Emacs 26.1 RC1 ok, and use it locally on the host fine. > > However, when attempting to ssh -X to host via PuTTY 0.70 and launch the Emacs gui (emacs -Q), emacs > is not displaying correctly.

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. > I suspect this issue is related to some combination of GTK and > Xming/VcXsrv, however the behavior does change between Emacs 25.3 and 26.1 RC1, see table below: 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? > Possibly related posts: > - > https://emacs.stackexchange.com/questions/40990/emacs-aborted-core-dumped-centos-7-0-emacs-25-3-please-help > > - https://bugs.launchpad.net/elementaryos/+bug/1355274 > - https://bugzilla.gnome.org/show_bug.cgi?id=85715 These don't look related to me, because the problems they describe existed before Emacs 25, which you say worked OK for you. Thanks.
