--- Comment #3 from Nils Fenner <nilsfen...@web.de> --- Actually I was wrong with the assumption of the parented window. The pcmanfm-qt MainWindow is a QMainWindow and unparented! Presumingly KWin makes the false assumption here that an application can only have one top-level window (parent == nullptr)! This is independent of window attributes and definitely a KWin bug. LXQt cannot workaround that! -- You are receiving this mail because: You are watching all bug changes.
