SUMMARY The KHamburgerMenu is a replacement for the menu bar of applications. In most KDE apps (e.g. Kalendar), the KHamburgerMenu vanishes if there is a global menu widget being used. This is not the case for KWrite. STEPS TO REPRODUCE 1. Add a global menu to any panel (Latte or stock Plasma) 2. Open KWrite OBSERVED RESULT KWrite has a visible KHamburgerMenu EXPECTED RESULT KWrite does not have a visible KHamburgerMenu SOFTWARE/OS VERSIONS 22.12.0
