What's the weirdest bug in a program you found in a project you didn't write? (programming.dev)

I thought of this after a recent bug I found. I use Vivaldi browser and recently it updated. After the update my mouse cursor was not visible when within the browser window. Other programs worked fine. I tried visual studio and steam and epic game store all had my mouse, Vivaldi didn't.

I closed all instances of Vivaldi via task nanager(was unable to click the x) and restarted it. That fixed the bug and I haven't been able to replicate so I don't have anything to submit for a bug report. Just a really strange thing.

What have been your weirdest bugs?

I don't see why they would do that when it's just an ordinary response from a random API: https://app.wafrn.net/api/v2/dashboard?level=2

I was thinking more scrapping off a browser, like using selenium. I haven't checked in a while but previously almost every element on a Google page had randomly generated id/names so you couldn't like automatically select the input box, type in a few terms and then click on the search button. If you got all the id's and tried, on the next loading of the page all the id's would be different.
