Maybe you can add an event filter and remove some of the events if

This. Separate your logic that decides an update is needed from the
logic that actually does the update, and have the former *queue* (if not
already queued) an event to do the latter.
I've used this technique on quite some occasions and IIUC Qt uses it
internally when repainting widgets (n.b. QWidget::update).
If possible, also move some of that slow logic to a different thread...
