Somewhere in the settings there is a touchscreen option to turn OFF the default little blue circle that shows up when you touch the screen. Turn that OFF! Max
All Settings > Ease of Access > Other Options > Touch Feedback
It didn’t help at all.
Go to control Panel Select pen and touch Click/select double tap or touch action click settings (a new dialog box will open) play with speed, duration, spatial tolerence etc.
It helped a little bit with double tapping. Nothing to adjust dragging, which is my main issue.
