Hey Christian,

Thanks for your reply.

I built a little test case and played around a little more. When I emit a QtSignal, which is connected to a slot where the resizing is done, everything works properly (with and without your provided patch). Still, with the patch, simply invoking a method which resizes the window fails.

Since I am definitely no expert on Qt, I can't really say if this is a genode-related problem or if I am using Qt improperly here.

I was not sure about that either, but found this interesting document, which states that GUI objects can only be used from the main thread:
