So, in wake of the scroll bug fix, I present to you, the newest mouse bug!
Previously you were able to press mouse 3 (scroll wheel) to run, and at the same time press RMB to turn in any direction, release mouse 3, and continue to turn while still having RMB pressed.
In this new patch, you're able to do all the above, except to continue to turn after releasing mouse 3.
I'm pretty sure I was able to do this pre-18.4.3.
So, another 2 months till this will be back to normal? And what about the ctrl -> alt switch?
