Text disappears when a filter is applied to FlxG.game

Hello everyone!

Based on that demo: http://haxeflixel.com/demos/Filters/ I tried to apply the scanline filter on my FlxG.game and that works as expected. Except for one point, after 7 seconds all the FlxText on screen disappear.

I do not have that problem if I apply the filter to only the camera.

The problem ocurs even if I compile to neko, windows or HTML5.

Anyone could help me with that?

I put my demo project here: demo.zip
