Was just giving 2.5 a shot on my Mac (snow leopard), and when rotating, panning, or zooming the viewport it shakes as if i were violently shaking my mouse. Happens when doing other stuff like trying to move a vert. Pretty much unusable, so haven’t tried anything beyond that =(
I’m using a wacom intuos3 mouse. I don’t have a reg mac mouse to try
Had to disable “continuous grab” in the “input” Preferences. Works fine now, but having that feature enabled would be nice… Wonder if it has to do with having dual monitors with different resolutions.
