Your NotebookLM query

The interaction between Apple Pencil Hover proximity events and touch input during finger panning often causes webviews to misinterpret touch contacts or trigger unexpected double-tap gesture events.

Since you've confirmed that disabling Apple Pencil Hover resolves the canvas jumping and turning off Enable double-tap eraser in pen mode prevents the tool switching[1], providing these exact reproduction details on the Obsidian-Excalidraw GitHub repository will be invaluable for Zsolt (the developer) to isolate and patch the hover event handling[2].

Describe the bug

When using the Excalidraw plugin in Obsidian on iPad, the canvas can unexpectedly jump or shift position when I rest my drawing hand on the screen after panning the canvas with a finger.

I hold my Apple Pencil using a dynamic tripod grip, with my ring finger and pinky resting on or sliding along the screen for stability. The side of my ring finger is typically the first part of my hand to make contact with the display.

The issue appears to be related to Apple Pencil Hover. When the Pencil tip is close enough to the display for Hover to activate, placing my hand on the screen can cause the canvas to shift suddenly.

Additional context

Grip: dynamic tripod grip.

Hand contact: ring finger and pinky rest or slide along the screen.

The ring finger’s side often touches the display before the rest of the hand.

The issue does not occur when the Apple Pencil Hover is disabled.

Steps to reproduce

Open an Excalidraw drawing in Obsidian on an iPad.

Ensure Apple Pencil Hover is enabled.

Pan the canvas using a finger.

Hold the Apple Pencil close enough to the display for Hover to be active.

Quickly rest the drawing hand on the screen, with the side of the ring finger touching first.

The canvas may jump or shift unexpectedly.

Expected behavior

Resting the drawing hand on the screen while Apple Pencil Hover is active should not move the canvas. The hand contact should be treated as palm rejection rather than as a pan gesture.

Actual behaviour

The canvas shifts or jumps across the screen when the hand is placed down while the Pencil is hovering.

Findings and workaround

Disabling Apple Pencil Hover in iPadOS resolves the canvas-jump behaviour.

The occasional switch to the eraser was a separate issue: it was caused by the Apple Pencil’s double-tap gesture, not by Excalidraw’s handling of Hover or palm rejection.

I am therefore reporting only the canvas-jump issue here.
