In game chat delay (at least on japanese language)

I have set pbe on japanese language and i have noticed a delay on chat. I type whatever I type and I can see it only after around 10 seconds and if the message is big after around 5 seconds it will display the half of it and after 5 seconds the rest.If i press z which should normally let me scroll up the chat it will show only previous messages and not the latest. {{sticker:slayer-jinx-unamused}}
