Please add an option to lock canvas rotation or to disable the rotation tool.
Disabling all gestures as a solution is unacceptable.
Disabling GPU/OpenGL usage as a solution is unacceptable.
Not all touch devices can disable rotation gestures, so suggesting to users that they use external software is also not an acceptable solution. For example, the Wacom 13HD touch does not have the "Standard Gestures" tab that allows the user to disable rotation gesture. This should instead be available inside photoshop.
I've got standard gestures on a Wacom Pro M but the options are greyed out. Can you try using a divverent driver that 'does' have that tab, and would it work if you did that? I've never liked gestures so never use them, even on my Cintiq Companion 2. It seems to me that if there is a work around that involves thhe Wacom driver you might find it on the Wacom forms.
Absolutely raise it on the Feedback site, but I have a feeling that when it comes to controlling particular gestures independantly, that is going to be tablet specific, and not something Photoshop can implement.
