Since releasing a preview build that includes the 1.2.14 framework, I’ve
received a number of complaints from users that when they look left or
right using the mouse, their view also goes up. For others, it always goes
down when looking left or right.
Replacing 1.2.14 with 1.2.13 fixes the problem. So does using windowed
mode. Has anyone else noticed this? I will do more investigation before
filing a bug.
