I was rather hoping to dee more of your widget code and in particular
what you are doing for draw() methods, that sort of thing.
There's not enough here to express any useful opinion.

How many threads are in your code?
Some of what you are seeing looks a lot like it might be thread
related rendering artefacts, if the code is not thread safe (though
that's just a guess as there's not really enough here to know.)
