So NOTOURBUG bugs stay forever open when upstream won't fix them?
Yeah. It also helps users looking for them since CLOSED bugs are by default not included in bug searches.
Specifically WRT this bug, it might make sense to reopen the bug if we think we can do something better in handling minified windows which don't get their X11 window unmapped, or change the resolution to INVALID / WONTFIX if we consider the relevant KDE setting as not supportable.
