Vert/horiz rulers, usually on left/top edges of window, appearing in middle of screen

[Rob the Slob]

Please see the attached screen grab. I don't know what happened to cause this. The rulers are crossed in the window. The usual rulers are still on the left and top of the window. Do I just restart my machine? Or is this some kind of feature I've never seen before and can reset?

Problem solved. Not so much solved as disappeared. So apparently something just glitched out. I restarted Photoshop and it was still there, which was when I posted. Restarted a second time and it was taken care of. Sorry for wasting people's time.

Apparently I'm not done wasting people's time. Because the problem is back. I've restarted my machine. What do I do next? Restart Creative Cloud? Find some plist to delete? This has just ended my progress on work that was due weeks ago that was just about to get done.

Others are also reporting this issue of "ghost rulers" and the engineers are aware of it. See this thread and upvote it in the upper right.

One solution there is to go to Preferences > Technology Previews > uncheck the “Enable Native Canvas Rulers” >  restart Photoshop. Tell us if that works.

Before getting this reply, I tried in order: restarting Photoshop (twice), restarting the machine (once), and finally, uninstalling Photoshop and re-installing. For all my complaints about CC moving to a subscription model, it has made the last option much less involved, if rather drastic . . . but that seems to have fixed it. I've turned off "Enable Native Canvas Rulers."

My case may be related to connecting to and disconnecting my MacBook from an auxiliary display, which moves windows around in all apps. I don't know, just the wildest guess. Praying very hard this doesn't come back, because I really don't have the time right now for tech glitches.

Thanks very much, jane-e and gener-7, for the replies.

Preferences > Technology Previews

That's not normal. I've never seen that in all the years I have had Photoshop.

Here's  a few things to try:

Use a different Workspace. Try "Essentials".  Window > Workspace > Essentials  If it is already chosen, then select "Reset Essentials." If you are using your own custom workspace, try resetting that as well.

Under Edit > Preferences > Technology Previews, checkmark "Deactivate Native Canvas." Restart Photoshop.

And finally, it may be due to a corrupt settings file. You would need to Reset Preferences:

Same problem, turning off "enable native canvas rulers" in technology previews sorted it but photoshop has become slow and bloat, and many of the changes more of a hinderance than an asset these days. When I can I am using affinity photo as much as I can.
