Just today I noticed a small pale white square on my screen. It's fixed in position, doesn't drag wider or open up anything.

Howdy yogadude,
Welcome to Apple Support Communities.
It sounds like the small white square on your iMac's display may be a pixel anomaly, take a look at the article linked below for more information and possible solutions.

Thanks Jason - I tired something even simpler and did a full shut down and reboot. Seems to have fixed the problem. Bit weird though.
No problem. I’m glad to hear it’s sorted.
I have the same thing. Comes and goes. It is an 8X8 pixel square that has a soft shadow. Cannot be moved or right clicked. Closing safari kills it but it returns.
NSA?
8 pixel drop shadow square for me too. Caused by safari, exiting safari it goes away. Seem nefarious. Definitely not a pixel anomaly. It's a white square with a drop shadow on it.
any other thoughts recently on this? I can get it to go away if I leave Safari but it has come back twice. Also, some people have mentioned screen sharing and I have used Screen Hero to share my screen but that doesn't make sense to me b/c it goes away when I exit safari. Screen Hero is it's own app, not running through Safari in any way that I could imagine.
