This is just what worked *FOR ME* in CSP, but it may be helpful for if anyone finds this thread in the future, as i have when i googled it and it was the first result.

Inside CSP, go to FILE(at the top left), go down the options and select PREFERENCES(Ctrl+K). A little page will open, click on TABLET on the side options and change the first option from WINTAB to TABLET PC. You'll then have to setup your pressure on your own, as this disables it.

If that doesn't work for you, you may try the 101% text scaling method but i doubt that'll do it. Here's hoping they implement a proper fix, it's been years. :P
