Mouselook doesn't work, related to a checkbox option
It seems related to the checkbox "Use instant window swapping (synchronizes game resolutions)". Mouselook works fine when the checkbox is checked but doesn't work when it's unchecked.
My layout has region 1 on the upper portion of the screen and regions 2-4 below it. I have three characters and they have region 2-4 as home regions. I'm on 38.4.603.1.
