I'm not sure, but maybe it is mod incompatible

I've removed BetterFonts and now I have a white blank square instead of a menu in mixer or factory.

Looks like there is stille a compatibility issue with some other mod. Can you confirm you're using latest MalisisCore jar ? If so, try to find what mod causes it so I can look into the problem.

I think it's my videocard do not support some type of image drawing, because i have this same bug with ThermalExpansion4 crafting indicators..

A you can't make a hook for weak PC's? I would be very grateful!
