1869968 - Pointer lock on windows makes the mouse go faster when the mouse polling rate is high

Status: UNCONFIRMED

(Core :: DOM: UI Events & Focus Handling, defect)

Description

[pfg]

Attachment: pointer-lock-bug-demo.html

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:120.0) Gecko/20100101 Firefox/120.0

Steps to reproduce:

1. Use a mouse set to a high polling rate, such as the logitech g502 hero set to 1000
2. Navigate to the attached demo
3. Move the mouse in circles. Notice that the black square perfectly tracks the mouse movements, albeit offset from the exact mouse position
4. Press 'enable pointer lock'
5. Move the mouse around, notice that the black square representing the cursor will sometimes move much faster than it should when you move your physical mouse.

Actual results:

The black square representing the mouse will sometimes move much faster than it would if pointer lock was not enabled

Expected results:

The mouse should move at the same speed it would on the windows desktop normally and not go really fast randomly.

Moving this to Core > DOM: UI Events & Focus Handling component to allow our engineers to examine it more closely. If this is not the right component, please move it to a more appropriate one. Thanks!
