Guys, I've come to understanding that the newest wacom drivers might not work properly on Windows 10, especially when it comes to cintiqs. Did anybody else get the problem of the weird calibration effect when the app you had to work on in on the tablet. Like, PC starts to think that the working space is between the displays when, in fact, it isn't.

Thing is, this problem is Wacom's fault and they acknowledged that their drivers, which a newer than version 6.3.29-x start to conflict with the basic Windows tablet drivers. There is no need to revert to copies of older system just because of that

So, for everyone else who got the problem, please, do check the preference to Tablet PC over WinTab in editor's options, whether it's Photoshop, Clip Studio or Paint Tool SAI (though some people who have SAI might need to roll back to the older driver since some versions of SAI lack the option of choosing what to use). This helped me and might help you
