In my opinion, it's worth trying to do a merge request for kio-extras. As for "approving" your suggestion, I think it's better leaving it to the kio-extras people because they know the code better than I do. In the meanwhile, I tried reproducing the bug in virtual machines with older Qt versions: I couldn't reproduce it with a version of KDE Neon using Qt 6.8.0 but it happened with a version using Qt 6.8.2, so I think it's something which happened between these two releases. Unfortunately, I think that the KDE frameworks version were different between the two cases, so I'm going to try writing a minimal Qt-only program showing this issue. I don't think I'll have time to do that before the week-end, however. -- You are receiving this mail because: You are watching all bug changes.
