This may be an issue with Qt6 and Wayland. This is triggered when the tooltip pops up while Doomseeker is out of focus.

Yeah, tooltips under Wayland are a bit screwy in general when Doomseeker is out of focus; they appear in their own decorated window that is centred on the main window. That affects both Qt 5 and 6.

It's possible the specific issue reported by this warning exists in Qt 5 as well, but Qt 6 is better at reporting these issues (from experience with QObject::connect warnings in personal projects)
