> it’s not about me, but about ways to improve the code
This is true for me, but I also would admit that it's not all altruistic.
Specifically, I will report problems that may be rare for others and unlikely to be reproducible by the maintainer. I often provide information about the operating system, version, etc. in those cases to put a reasonable amount of effort into it, but I don't always expect it to be fixed by the maintainer.
However, if I determine later that the bug was caused by something else, I'll go find the bug I created and add a comment indicating that it was fixed or related to another problem, if it's simple.
