[severity:It's more difficult to complete my work]
When NET6 performs TouchDown events for the first ten times in the upper left corner of InkCanvas control in WPF program, a cable-stayed line appears. The cable-stayed line persists during TouchMove and disappears during TouchUp.
The device I am using now is Surface, the Windows system version is Windows10 Home Edition, the internal operating system version is 19045.4170, the target framework of the project is net6.0-windows, and the target runtime is win-x86. The line does not appear when drawing with the surface pen. It only appears when you Touch the top left area of the control with your finger ten times, and it does not appear with the mouse. This phenomenon has also occurred before when running on a large screen machine.
We look forward to a solution to this problem.

That's helpful, thanks! I noticed you created a separate issue #9781, so one of them should be closed as duplicate.
