I tried, doesn't help.

Actually, it doesn't work with GPU turned off. It gives completely the same set of problems. You can see it in the video.

*Dominic Michael in this case the app would work, but it would not help fixing the underlying issue for other users as well. It can be useful to work, but I hope that @frafilipo art would continue helping the Ps team fix the issue.

Hello, try this: first hold Alt, then go to the menu.

It is still producing the same set of problems, even with GPU turned off.

I made a video with CPU scenario, you can see it below.

@frafilipo art , Can you please try the same scenario in CPU mode?

How to enable CPU mode?

1. Navigate to the menu, Edit --> Preferences --> General
2. Select Performance
3. Uncheck "Use Graphics Processor"
4. Click Ok and save the settings.

The second video is with the latest drivers.

You are welcome. I made a video in which I demonstrate the problem  after using Liquify and pen. All the tool (marquee tool, text tool... you can see in the video how other tools are misbehaving) go crazy. BUT!!

I discovered by accident that if I use the brush tool and draw something, it will cure the problem completely. Weird, isn't it? But, if I open another document and try Liquify while using the pen, the problem will start again. As soon as I use the brush tool to draw something, the problems go away. At least temporarily, until I open another document. I hope this will help.
