You can sure mention bugs here and we can discuss it, but I doubt any developers are actually watching this community. Reporting a bug here is not the right way to actually request that a developer resolves it.
I like to use PieFed to discuss software bugs with other users to determine if it is actually a valid problem and worth posting a formal issue report on their git repo or whatever.
This seems to be the formal way to report bugs for this project: https://www.gimp.org/bugs/
