Slick2D&LWJGL Font Rendering

Hi guys, I’m trying to render text, with Slick2D, but when the window starts the text appears for couple of ms and after it’s turned white.
Here is a picture with situation.I can’t figure out what is wrong:

EDIT: If i don’t unbind the textures the font overlap with part of one texture.
