Is Anyone Else Getting Lag When Wrighting Long Articles?

I have only tried this on my 2 machines but i have received exactly the same problem, when writing a particularly long article (still unpublished) Steemit becomes quite laggy, when typing text there is significant delay in using the keyboard and when scrolling up and down the article there is also lag, the more text i input the more the lag increases. Nothing else open in my browser is laggy only Steemit. I have tested this on windows and linux both on good quality hardware with fast internet and the problem is identical, has anyone else encountered this problem? And does anyone know how to fix this or should i contact the Steemit Dev's?

Thanks
