When I run Hopalong using the DRM backend on one VT, switch VT, open a terminal and start a program to open a window on Hopalong, then switch back to Hopalong's VT, Hopalong segfaults.
Steps to reproduce:
Run Hopalong on tty3 (wayland-1)
Switch to main desktop on tty2 (wayland-0)
Run WAYLAND_DISPLAY=wayland-1 weston-terminal
Switch back to tty3
Hopalong segfaults
I haven't got the full backtrace but gdb's top line is:
