I have encountered a bug that makes my mouse clicks not responding properly in game. For example, if I click move then it ignores my next few clicks and just kept moving to one location. Or after casting a skill the character would just stand and do attack without picking up my click to move. It gets worse during fight but happens even at the start.
Thing I had tried
Windows 10 Disable Scroll inactive windows when I hover over them
Reinstall mouse driver
Uninstall GeForce Experience (GTX970)
In game windows full screen mode
Tick Reduce mouse lag option
Lower graphics setting
Change mouse frequency
Changed power setting
Changed USB port
I have done everything I can find. Any ideas?
