In BIOS screens, the KVM remove mouse cursor is not aligned with the local mouse cursor

Describe the bug 🪲

In BIOS screens, the KVM remove mouse cursor is not aligned with the local mouse cursor.

I'm testing with this hardware:

  • HP EliteDesk 800 G2 DM 35W
  • BIOS N21 Ver. 02.60
  • AMT 11.8.92

To Reproduce 🪜
Steps to reproduce the behavior:

  1. Boot the computer to the BIOS.
  2. Using the KVM UI control (or at the sample-web-ui), move the mouse.
  3. See that it has an odd offset. In the screenshot below, my local computer mouse cursor is the black one. the white one is the remote computer mouse cursor. As you can see, they are not aligned, and have an odd offset between them.

Please note that this only happens when in the BIOS screens. When the remote computer is at the OS desktop, the mouse cursor works as expected.

Expected behavior
I expected the remote mouse cursor to follow the local mouse cursor.

Additional context

I'm not sure how the mouse is emulated in AMT. As a comparison, https://docs.pikvm.org/mouse/ talks about different mouse types: absolute or relative. Maybe there is something like this with AMT?
