Right click on Desktop, Add Panel, Application Menu Bar OBSERVED RESULT EXPECTED RESULT SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
What Plasma version are you using? What's the contents of your ~/.config/gtk-3.0/settings.ini file? Do the buttons reappear, if you remove application menu?
Plasma 5.17.80, I am running KDE Neon Unstable for testing. Here is my Gtk3 settings.ini file. [Settings] gtk-application-prefer-dark-theme=0 gtk-button-images=1 gtk-cursor-theme-name=breeze_cursors gtk-decoration-layout=icon:minimize,maximize,close gtk-fallback-icon-theme=breeze gtk-font-name=Noto Sans 10 gtk-icon-theme-name=breeze gtk-menu-images=1 gtk-primary-button-warps-slider=0 gtk-theme-name=Breeze gtk-toolbar-style=GTK_TOOLBAR_BOTH_HORIZ If I remove the applications menu bar the buttons reappear.
I have the same problem. The window control buttons are scrambled for me in Firefox only. Other GTK applications work fine. Note: This only happens if a custom GTK theme is used. The default Breeze theme works fine. Also using KDE neon testing. settings.ini [Settings] gtk-application-prefer-dark-theme=1 gtk-button-images=1 gtk-cursor-theme-name=breeze_cursors gtk-decoration-layout=icon:minimize,maximize,close gtk-enable-animations=0 gtk-fallback-icon-theme=gnome gtk-font-name=Noto Sans, 10 gtk-icon-theme-name=Papirus-Dark gtk-menu-images=1 gtk-primary-button-warps-slider=0 gtk-theme-name=Mojave-dark-solid gtk-toolbar-style=GTK_TOOLBAR_BOTH_HORIZ

Updated my system today and the window controls appear now as they should.
I am still having that on my test install. Maybe I haven't gotten the update yet.
Same thing on KDE Plasma 5.18 (KDE Neon 5.18, KDE Frameworks 5.67.0, KDE Applications 19.12.2, Qt 5.13.2, clean install)
I'm having the same issue but with the Git Master builds for openSUSE Krypton repositories. Firefox does not have Close, Maximize and Minimize buttons if a Global Menu is present.
I had the same issues when I was using the unity-menubar patch on Firefox. It also happens with Thunderbird. The following code on userChrome.css solved the problem on Firefox but I don't know about solving the cause: @import "customChrome.css"; /**/ #toolbar-menubar[autohide="true"]:not([inactive]) + #TabsToolbar > .titlebar-buttonbox-container { visibility: visible !important; }
This is a bug from Firefox and the global menu patch side. You should report it to the team that maintain that patch. A workaround: https://gitlab.com/Thaodan/firefox-kde-opensuse/-/issues/8
