Hey Usus, I haven't noticed any problems like this in my game. Have you tried the normal computer troubleshooting steps? 

Firstly make sure you clear your cache, check that your Java version is up to date, you can check everything here: https://www.whatismybrowser.com

If these steps do not work test the game in another browser such as Firefox or Chrome. King have made a really good video to help you troubleshoot these problems, check it out:https://www.youtube.com/watch?v=OESCE4Jj2tU

Let me know  how you get on and if it makes a difference.
