We're really sorry for the hassle. Since how long you are facing this issue? Please check that you are using the latest version of Wacom drivers. You can check for the latest drivers on the manufacturer website.
I´m using the last one (6.3.29-6). I´ve noticed the strange behavior 2 or 3 days ago. I don't remember having problem before that, when I was using 7.3.
Already tried to disable "Use Windows Ink" on Wacom panel, but didn't helped.
Strange is that other apps is OK.
Could you please check if there are any pending Windows update on your machine. If you see any pending updates, please install them and restart your machine and check if that helps.
No updates available.
The last "change" i remember I did on my PC was changing the registry using the command bellow to solve the problem with the tablet on Photoshop (tablet moving the canvas instead of painting).
Can it be related?
This registry, btw.
reg add HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Pen /v LegacyPenInteractionModel /t REG_DWORD /d 1 /f
