After the update to Photoshop CC 2020
(now 21.1.2), there are problems with working on the Wacom tablet:
elements (especially smart objects and layers grouped in group
folders) jump back and forth when moving and cannot be placed
precisely.

This happens on several computers with
different tablets.

This does not happen with other
programs (inkluding Photoshop 2019, Adobe Illustrator CC 2020,
Indesign CC 2020, Open Office, operating system and including
Photoshop 2019).  


The mouse is working proper.

I had called the Adobe support before
and was finally referred to Wacom. After writing extensively with
Wacom Support and performing various tests without success, I was
referred back to Adobe (because the problem is only in Photoshop) and
write with the Adobe support again – but without result. Now they
send me to the forum.



My Setting (s):


x Wacom Intous 4 XL (PTK-1240)…

When using tablet to manage path items or adjusting crop frame etc, the  
pressed cursor suddenly starts to jump (see linked video). The trouble
has been appeared since v.21.2.2 update on Windows OS.https://community.adobe.com/havfw69955/attachments/havfw69955/photoshop/462911/2/azbuka-119A8780.psd%20%40%20300%25%20(Layer%200,%20RGB_8)%20_%202020-09-07%2018-46-29.mp4
