Comment # 5 on bug 1115541 from Fabian Vogt

(In reply to Fabian Vogt from comment #3)
> This is already fixed in Qt 5.11.1 and up with a combination of
> 67227aeffdf94be8d177309d27291d5b3247586c ("xcb: fix regression with remote
> X11 clients") and 5f1df771b6ea267b75553fce870d0c6bbe5e38ca ("xcb: re-factor
> QXcbConnection::printXcbEvent").
> 
> Unfortunately those are not feasible to backport (not even parts of it) and
> the patch attached to the Qt bugreport does it in an incompatible way, so it
> shouldn't be backported either.
> 
> I guess we would need to write a hack^Wpatch ourselves?
