[Bug report] Dot appears at start of pinch gesture on physical device

[enoiu]

Thank you for your response and update.

After upgrading from version 0.9.5 to 0.9.8, the pinch gesture issue on the simulator has been resolved.

However, on a physical device (Pixel 8a), a dot appears at the start of the pinch gesture, as shown in the attached video. In version 0.9.5, this dot was not displayed.
