[X2Go-Dev] Broken glyphs and icons after suspending a session

[Jim Burnes]

If the glyph breakage is because of my patch it's probably because the
patch is rather non-selective.  If nxagent's render code tries to reference
a null pointer I prevent it from doing that.

I'm not specifically aware how that might break your glyphs, but if it does
I suspect it's because my code is preventing remote synchronization of the
rendered object.  Look at all of the conditionals in the patch that perform
a sync operation if true.

I wonder if someone like Keith Packard could help.  Perhaps if we point the
nomachine guys at our patch they might suggest a cleaner fix.

...or it might be completely unrelated to your problem.  :-)
