Title:
xwininfo crashed with SIGSEGV in Select_Window()
Status in x11-utils package in Ubuntu:
Fix Released
Bug description:
I was trying a GNOME Wayland session and was using xwininfo to tell
which windows where using XWayland and which windows where using
Wayland.
At first it worked well but after a few uses it crashed and I could
not use it any longer (it could not grab the input).
