I don't know how valid is that nowadays; but I recovered it recently - and it is a clear-cut stacktrace.
May still be valid.
That's odd, the X11 shadow servers only ever exports one window covering all monitors, but this stacktrace comes from the client sending a configure packet with an invalid window id. Where would it get this from? r26031 will now log the invalid window id.
How can I reproduce this?
As I said

I have stored this stacktrace somewhere to report it sometime, but it kinda fell through the tracks.
I will be on the lookout (as always) if anything comes to the console
Let's close it for now, re-open if we see it again.
