Japanese language slowing down WEC7

Technical Support

Greetings,
using WEC7 on VF61 I noticed that our application is slow and not always responsive while displaying Japanese language text. If used with any other languages (English, Italian, French, etc.) it works fine.
Everything in the application is the same except the displayed strings.
Is there a way to make it faster?

I will upload a video showing the problem:
