Follow-up Comment #5, bug #53328 (project octave):
I tracked the issue down to ObjectProxy.cc. We use the following contruct to
call a function in the GUI thread from the interpreter and retrieve a return
value:
QMetaObject::invokeMethod (m_object, "slotGetPixels", t,
Q_RETURN_ARG (uint8NDArray, retval));
Sometimes this function fails and the "slotGetPixels" in the GUI thread never
gets executed. QMetaObject::invokeMethod returns false if it fails, this could
be used to explicitly warn about the failure, but I didn't find a clue on the
actual reason for the failure.
