The first is an old debug routine that I thought I'd put into a patch, but I guess not. The second one is also known but is a bit more mysterious and a problem that existed in the default game as well (for PC at least); it can happen in several places, including Bugenhagen's Observatory, the second screen of the game, and I can't recall where else.
As for sub-threads, it's tricky on Qhimm because we don't have sub-boards for them so a bug thread would probably get buried after a while. There's a sub-board for NT on Insane Difficulty.com which has multiple threads, including one for bugs. That helped separate the posts up a bit.
