Basically copy/pasting my question from forums:
Newest preview 8 made so that mouse axis getters won’t give any values if mouse cursor is set to be visible.
In 4.10 the behavior was strange as well requiring you to hold any mouse button down for value to update if cursor was visible.
4.11 was great so far with no weirdness - axis values updated without needing mouse buttons to be held, but now it doesn’t work at all if cursor is visible.
Are these changes intentional(why?) or is this a bug?
I use this setup for testing:
