Some time in Google chrome we press F12 for responsive mode, then mouse pointer does not show. There is big problem for a front end developer or a php developer who is testing the website in Google chrome. The solution is here
there are 3 dots ⋮ on top right corner as u can see in the image attached below. After you click on that. You will find a dropdown, in which u have to select mobile ( no touch) option.
Go to: Control Panel > Intel Graphics Settings > Display > General Settings. Then change Quantization Range to Full Range.
