This issue occurs when the Snap to Item feature is activated in an app that doesn’t support it (common in 3rd party apps).

Assign the Snap to Item feature to a hot corner. This allows you to switch from Snap to Item mode to regular pointer usage by focusing your gaze on the hot corner.

Alternatively, turn off Snap to Item in iPad Settings: 

  • Go to iPad Settings > Accessibility > Touch > Assistive Touch > Devices > Snap to Item OFF.
