Exclusion blend mode delay bug

Hi,

i would like your help with this problem:

Idea: I want headline over image. Sometimes there is contrast problem so i decided to use Exclusion blending mode. It works fine when headline is white, background behind type black, blending mode Exclusion. The effect looks exactly how i want since i want it to be clean but little edgy.

Problem: everything works fine but there is a "bug" with original white type and black background appearing for a moment before blending mode takes effect.

I need to figure out a way to achieve this kind of effect without the blending delay. I have attached video so you know what I'm talking about.
