If you need Emacs to be able to recover from closing displays, compile
it with the Lucid toolkit instead of GTK.
+** Emacs compiled with GTK+ 3 crashes when run under some X servers.
+This happens when the X server does not provide certain display
+features that the underlying GTK+ 3 toolkit assumes. For example, this
+issue has been seen with remote X servers like X2Go. The symptoms
+are an Emacs crash, possibly triggered by the mouse entering the Emacs
+window, or an attempt to resize the Emacs window. The crash backtrace
+contains a call to XQueryPointer.
+
+This issue was fixed in the GTK+ 3 toolkit in commit 4b1c0256 in February 2018.
+
+If your GTK+ 3 is still affected, you can avoid the issue by recompiling
+Emacs with a different X toolkit, eg --with-toolkit=gtk2.

** Emacs compiled with GTK crashes at startup due to X protocol error.
This is known to happen on elementary OS GNU/Linux systems.
