I'm not sure that's related. What do other Qt5 applications show (if they run), like Qt's Assistant for instance?

If they too get stuck on this or a comparable error, the 1st thing to try would be to move aside all .conf files from etc/fonts/conf.d .

FWIW, I'm also seeing QXcbShmImage smget errors when I use the XCB qpa plugin on OS X, but they're apparently benign.

And that brings me to the 64k$ question: is it expected that Qt5/KF5 applications use X11 under Cygwin, rather than some native display engine (QPA)?
