It's been mentioned before, but I'm creating a dedicated topic in case it was missed. In 5.4 the wheel preset always defaults to Saber's preset corresponding to my wheel, not the custom preset that I chose last time. In 5.3 this used to work correctly.
What's worse, you can't use the arrows to switch back to the custom preset. You have to initiate a button change to restore the custom preset. This then leaves the mouse cursor in the middle of the screen permanently when looking around.
