TSG: Delay and straight lines or gaps at start of stokes
Overview
This problem happens on Windows due to some interaction between the Windows Ink system and an application that uses the pen.
Symptoms
When drawing a stroke (for example simple curve). You may notice that the there is a slightly delay before something is drawn. The resulting stroke will either:
(a) skip over the beginning part of the stroke
or (b) have a straight line drawn from where you put the pen down to a little latter in stroke.
Other manifestations
The same delay at the beginning of dragging the pen, can manifest in other user experiences. For example, you might see it as small delay when first moving a slider. As you move the pointer with the pen, the slider will not move for several millimeters and then suddenly snap to the location of the pen.
Examples
Diagnostic questions to answer
Does it happen in a specific app or all apps?
Does it happen in this online app? 7P online tablet tester
Does it happen in the driver pressure test region?
Potential solutions
Restart the computer
Try disabling windows ink in the app then restart the app
and if that doesn't solve it, then also try disabling windows ink in the driver and then restart the app.
