Photoshop: Using color picker/eyedropper shifts/scrolls canvas

Since "upgrading" to 2020 I and a friend have had an issue where occasionally--I can't always replicate it on demand--the color picker, whether using the tool or a keyboard shortcut, will attempt to grab the color and then immediately revert back to another. It will do this sometimes dozens of times and after changing tools, and if you click on the canvas/draw with the stylus during this process it will draw a series of zigzagging lines as if the pen has been shift-clicked from off the canvas.

Additionally, if you are zoomed in when this happens, it repeatedly pans the canvas slightly to the right.

I keep seeing mentions of dual monitor set ups in association with this, which also applies to me and the friend having the same issue--we both use dual monitors.

I have tried selecting legacy compositing to see if this fixes it, but legacy compositing causes an unrelated layer movement bug in the latest release so I've had to disable it again. Lovely!

This is exactly the same behavior I and my friend have observed. I have seen three different tablet brands associated with it (Wacom, VEIKK, and Huion) so I do not believe it to be a tablet driver problem. So far it seems reports are coming in from Windows machines. Again, it may be related to a dual monitor issue but I can't confirm it yet.

This has been reported several times through various routes and on Twitter and keeps being dismissed as a tablet driver issue unrelated to Photoshop, or a one-off fluke that needs to be fixed by restarting. Clearly, this is not the case.

POSSIBLY RELATED: I am having an issue also where occasionally using the marquee/selection tools occasionally causes PS to "insist" that I started the selection from an arbitrary point on my canvas. It will continue to start the selection from that arbitrary point until I close the file or click enough other tools that it randomly starts working again. Usually I have to close and reopen the file. As both issues seem to indicate that PS is registering clicks outside of the area they are actually occurring, possibly they are related?

Update:
While working today I have found that if you switch clicks between the mouse and the tablet it "shakes it out of it" and you can use the eyedropper normally again for a while until it happens again. Just clicking with either one doesn't work--you specifically have to click one, then the other, then the other.
