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?

Yeah, to be fair, there was an issue getting string.h to work (so i could just use strstr) with the vendor's shitty toolchain, that took me talking to an engineer at the vendor, and the dev who wrote that was out of our Taiwan office. But also, my first fix was just doing a sort of sliding-window check, manually checing for s[0] == '\n' && s[1] == 'C' && s[2] == 'o' &&..., which was gross, but much more correct.

Wait...not being able to use a basic library like string.h opens up so many other questions

🤷, embedded device manufacturers were really bad at software back then. I honestly don't remember the details anymore.

The only words I don't believe there are... Were and back then
