Since I got my drawing tablet (One by Wacom CTL-472) I've been having some issues with using the Control+Z (Undo).
It does not lag when drawing or using other features, but when i especifically press Control Z when im drawing with the tablet, it does a lag. It goes from 10 - 40 seconds lag, and it break all my workflowing. Already tried using my drawing tablet in others drawing apps, but nothing especial happens, its just with photoshop. Also already tried to alocate more RAM to it, but it still not works.
Also already tried messing with the configurations of cache and historic. Nothing worked.
When it lags, photoshop freezes, and i cant change the tool that im using, or select anything else. Sometimes, when i draw doing the period of the lag, it catches up after the lag moment.
