bug at begining of the game

There is a bug at the begin of the game. It takes 3 to 5 seconds. so if i want  to play 1 min game or 2|1 and i start with white i allways start with a few seconds less. i am using chrome 

if i do a premove of taking piece back and grab a horse or another piece, and the premove can not be done the piece is un grabbed so i have to grab and move it again. in the case of a horse it is a bit more difficult cause i can not do L move very fast. 

is somebody else with this problems??

You may want to close some of your apps, as well as some of those browser tabs.

Thanks but didn't solve for a long time. Only in the first games.. 

I've never seen anything like that before. First thing to do is try clearing your browser cache. But you likely have some kind of software/plugin/add-on that is interfering with some of the site scripts and might be causing as least some of what you are seeing.
