I dont have this problem, maybe you could post a snippet of your code
which does this for you.

Currently I have to fill the area behind the text using a rectangle primitive and then overlay the text, and of course this doesn't happen instantly so between the 2 operations you get background color only on the screen... and thus flicker. Yes I know double buffering fixes this, but the speed + memory hit is a bit much for simple things like standard GUI widgets (tree/list/button etc).
