Mouse-drawn circles become oval with asymmetric diagonal movement when sitting on cushion.

Issue:

When using a mouse to draw "circles" while sitting on the cushions, you will notice that the movement from upper-left to lower-right is greater than that from upper-right to lower-left; however, when not sitting on the cushions, the movement is normal.

Reproduce:

Place a cusion down, using a mouse to draw “circles“, but instead become a oval shape movement. Then place shift to leave the cusion, the movement become circles again.

Expected outcome:

Player’s head movement will draw a circles.

What actually happened:

Player’s head movement draw an oval (movement from upper-left to lower-right is greater than that from upper-right to lower-left)
