Now I have used it for many weeks, including with stable Debian 13 Trixie. The problem persists.
Often it downloads a large file (10 GB and larger) without detecting any error. But after manually asking Transmission to “verify local data” on completed torrents, it detects that one or two percent of the pieces are broken and starts re-downloading the missing pieces. In videos, it often goes unnoticed but then it shows artifacts. That's how it got to my attention. Regards Stephan
