My clone tool source point has disappeared. Thinking it was a problem on a very old tablet I have got a new one (Wacom Intuos). Problem still there so last night down loaded latest PS 21.2.4 . A quick check and all seemed well. However, today it is not working again. Everything ok if using the mouse but I want the accuracy of the pen. What has gone wrong? The source is staying in the start position and hot following the movement.
Are you sure your using Phoroshop 21.2.4. There was a issue like you describe when Adobe broke Photoshop WinTab support but that bugs should be fixed in Photoshop 2020 version 21.2.4. Here how you configer an intusos on Windows. Also someone Posted today that there is a problem with Photoshop and Wacom latest driver 6.3.42-2 that they had to restore the preverious version which is the one I have installed 6.3.41-1
