lags in browsers

Need Help! My problem is very serious and requires urgent solutions. If you down any key on the keyboard (such as Shift) and will lead the mouse a couple of seconds, you will see that the cursor (png cross) begins to lag behind (in fact: whole game). I noticed that all the action in game look likes in the water, although the FPS not falls. Chrome works fine. The most evident problem in the microsoft edge, and ms explorer

I haven't noticed any lag when using Internet Explorer, sorry.
