Bugs we can reproduce, or which cause we understand are usually fixed very easily.
It is important to mention whether a bug happens “always”, or “sometimes”, and what triggers it.
If a bug happens but didn’t happen before, or doesn’t happen in another distribution, or doesn’t happen in a different environment, please mention it and try to pinpoint the differences at play.
If we can’t reproduce a particular bug and we don’t understand its cause, it’s unlikely we’ll be able to fix it.
