Thanks for posting about this. It is somewhat random bug (it doesn't seem to be happening to everyone) that the engineers are currently trying to duplicate in-house and fix.
Some people have had success eliminating it by uninstalling/reinstalling Fresco. If you want to try that, please just first make sure that all of your work shows up in https://assets.adobe.com/cloud-documents.
The same issue appears on my Surface Pro 5. I wonder if it only happens in Win 10 or it also happens to iPad users. Besides this also happens when I use Photoshop.
I was having the same issue. An adobe rep got me to uninstall and the problem went away.
I later found out that the issue was because of the "Hold Down Pen For Straight Lines" beta feature.
When this is on - green dots, when this is off, regular dots 🙂
Thanks, this solved my problem!
I am using a surface pro 5 i5 model
Thanks for posting Garnet.
This is indeed the problem. And the team is working on a permanent fix.
