This conversation has been merged. Please reference the main conversation: Photoshop CC 2019: With rulers show, brushstroke creates a straight line as if Shift was held down (macOS)

clone stamp and healing brush with Wacom Intuos tablet sometimes freeze after Opt+Click, then a straight line shows up between the frozen clone source abd the brush cursor. here is a video showing the problem:

The issue is resolved only by turning off the ruler. 

I have experienced it on MacPro 2013 running 10.14 Mojave and on brand new MacBook Pro 16, 10.15.2 Catalina, only running latest Photoshop 21.0.2 and latest Wacom Driver 6.3.38-2. Nothing else yet installed.

The problem doesn't exist on MacPro 2013 running 10.12.6 Sierra.

Also testes with Wacom Intuos 4 XL (PTK-1240) and Intuos Pro M (PTH-651)

I'm aware that there were some issues with the ruler, but thought that thew are resolved in the last version. Adobe please, this is a serious issue. It is not possible to work like this.

Many thanks!

Brush Tool and Clone Stamp Tool display intermittent stark misbehaviour for me, too. 
As concerns the Clone Stamp Tool I did a Screen Recording and noticed only when scrolling through  it slowly that in the instances when the Clone Stamp Tool behaves nonsensical after picking up a source by alt-clicking
• the next clicked point itself seems to be honored
• but the tool then seems to shoot in the direction of the position of the clone source instead of following the actual cursor.
(Unfortunately it seems impossible for me to upload even a downsampled gif on this Forum today.) 

Several of my colleagues and acquaintances who work on Mac seem to be hounded by the same misconduct.
