StaticText window does not adapt text rendering area correctly when a scrollbar is set, for example take OgreTray statictext and activate the vertical scrollbar manually when the box contains a lot of text that goes outside the windows area. The text will be under the scrollbar when the scrollbar is first set. When you resize the window it suddenly displays it correctly.
Steps to reproduce: 1. Create OgreTray/StaticText window 2. size it so it is not too big 3. add a lot of text 4. set vertical scrollbar to on 5. observe text being under the scrollbar 6. slightly resize the window 7. text shifts correctly
