thank you soooo much for your solution. It's work!
I try to fix it for 2 days and even buy a new wacom :(
Might be that the way wacom try to boost their sales. :)

I too am having the same issue with my Intuos Pro model PTH 660 after updating to a MacBook Pro running Catalina. Until I connected my Apple trackpad I thought my graphics card's refresh rate was messed up.

I just had the same experience, except I'm running macOS 10.14 Mojave.

  • Updated from driver version 6.3.37-3 to 6.3.38-3 - straight away my pointer became juddery and jerky, jagged and flickery, severe reduction in fps, lack of precision, totally unusable
  • Downgraded driver back to 6.3.37-3 - pointer movement was smooth again, normality was restored.

This was a rather traumatic experience, and reminds me of how dependent I am on Wacom as an ex-RSI sufferer. I use a pen & tablet as my regular pointing device. Have been for 20 years, and cannot work without it. So having something like this happen is like having my right arm cut off.

I don't think this has anything do with macOS 10.15 Catalina - I'm not running Catalina. I'm still on 10.14 Mojave. All I did was driver upgrade the driver and then downgrade it again.

A question for Wacom: what changed between driver 6.3.37-3 and driver 6.3.38-3? Whatever it was, the culprit seems to involve driver version, not macOS version.

6.3.38-3 uses an additional driver, so now there are three running processes... in previous releases it has used two.
