While trying to reproduce bug #1398234, I thought of running mate-terminal under my GNOME session, which uses Wayland, and it led to a crash of the mate-terminal with the below backtrace: Thread 1 "mate-terminal" received signal SIGSEGV, Segmentation fault. slowly_and_stupidly_obtain_timestamp (xdisplay=0x5555557f9090) at terminal.c:449 449 xwindow = (gdb) bt #0 0x000055555556a98c in slowly_and_stupidly_obtain_timestamp (xdisplay=0x5555557f9090) at terminal.c:449 #1 0x00005555555679f3 in main (argc=<optimized out>, argv=<optimized out>) at terminal.c:605
Wayland is like disko 3000 for me. I don't expect that MATE upstream will support wayland until this report reach EOL. Patches are welcome.
Right, I see. I just wanted to mentioned it, when I noticed it. Feel free to close it. With respect of a possible fix (even I do not know how much doable), it would be to not use X calls directly, but use some slightly higher-level API, like gtk+/gdk, which hides the details of what backend is used. One thing is weird to me, I thought that xWayland would catch this, but my knowledge of Wayland internals is very close to yours.
Can you please open an upstream report for it with all neccessary infos like distro, distro version, m-t release? https://github.com/mate-desktop/mate-terminal Maybe it's possible to backport a change from gnome-terminal. Not sure about, do we see X-wayland or wayland in f25 gnome default session. And does gnome provide an X session as fallback. By the way, someone told me that a lot of applications don't run in gnome any more for this reason.

Yes, you can choose whether run GNOME Shell with Wayland (default) or with X. At least gdm provides the options. I'm not currently sure how lightdm.
