I’ve had this bug/glitch before, but always managed to avoid it one way or another, but not this time.
In my application, when opening a modal dialog, I get some really strange behaviour. Parts of the dialog flicker or are even missing and the underlying view can partially been seen.

Currently using macOS Sierra (but also had this issue on previous versions), Chrome version 53.0.2785.143 (64-bit) and Vaadin 7.7.3.
I have no issues if I change any of this to either Safari or some Lunix distribution.
It can be recreated on the Vaadin Valo-theme demo page : http://demo.vaadin.com/valo-theme/#!common
When you open a dialog with ‘closable’, ‘resizable’ and ‘modal’ selected.
Open the dialog, start enlarging it and it will happen at a certain point.
UPDATE:
If I fill the dialog with components that are full sized, I don’t get the issue anymore. So far. I’ll keep on testing.
