[SOLVED] White Pixel Stuck In Center of my Gnome Workspace?

There is a white pixel (or block of 4 pixels? idk) stuck in the center of my Gnome workspace. It persists across reboots, and appears even on a fresh login before opening any other apps (but not on the login screen itself). It only appears on my primary workspace and disappears when I open "Activities" view, though it comes back when I exit that. If I use my laptop's touchpad gestures to swipe between workspaces, the dot slides with the primary workspace and the second workspace does not have it. It always stays fixed in the exact center of my screen, regardless of where I move windows around or what apps are opened. It only started happening a few days ago, though I don't know what might have caused it.

How can I troubleshoot this? It doesn't seem to be interactive (that I can tell) and always draws over every other window/app on my screen so it's pretty annoying.

Maybe gnome now has a tracking pixel

Is this gnome on xorg or gnome on wayland?
For gnome on X11, xprop/xwininfo may help to identify the client that puts it there.

Re: [SOLVED] White Pixel Stuck In Center of my Gnome Workspace?

So I figured out that it was a gnome extension I had installed. Specifically the Peek Top Bar on Fullscreen extension. It recently had a new version pushed to improve Wayland behavior but I guess it also caused this white dot. I've filed a bug with the extension's project.

And I should have mentioned in my original post, but I'm running on Wayland.
