How to cope with slow rendering of widgets in Ext GWT (GXT)?

I have a window with several widgets inside. When it is displayed, it shows in the upper left corner for a second and then centered.

Is there a chance of lazy rendering? I mean, the window is first centered, and then the child widgets are displayed. Or maybe I can hide the contents of the window behind the mask during rendering?

DeferredCommand may help the situation a bit, expecting all current events to be processed - so when the window is displayed this time, the browser may be less loaded.
