windows 10 does have its little problems,the only way i know of that works pretty good is to only play with the game window open,also download ADBLOCK this stops ads popping up on the scorecard screen,they can add to the problem,its NEVER going to be perfect after all it is only a browser game,i have windows 10 ready for download but i am not going to take up the offer,i use chrome .
little tip...try taking a 2 sec pause at the top of your backswing ,it does help,it gives time for the WGT servers time to catch up
