SUMMARY Can reproduce on Arch Linux and neon unstable. STEPS TO REPRODUCE 1. use Wayland session 2. make sure 'Close windows by double-clicking the menu button' option is checked in 'Titlebar buttons' tab of Window Decorations KCM 3. install any of the following apps: BiglyBT torrent client - available on flathub.org Deluge torrent client - available on flathub.org Tixati torrent client - .deb and .rpm packages available on https://www.tixati.com/download/linux.html JDownloader - available on flathub.org 4. open the app installed in the step 2 and maximize its window 5. double-click on the app icon in the window decoration OBSERVED RESULT nothing happens. If the window of the app is not maximized, it closes after the double-click on its icon, as expected. EXPECTED RESULT 'Close windows by double-clicking the menu button' feature should always work SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.25.3 KDE Frameworks Version: 5.96.0 Qt Version: 5.15.5 Graphics Platform: Wayland
Does the menu button do anything at all? A bunch of X11 apps place an invisible 32x32 window on the top left of the screen, which would explain this
If the windows of the apps mentioned in the step 3 are maximized, no context menu opens when I right-click on their icons in their window decorations. The context menus open as expected if the windows are not maximized. Thiis does not occur on X11. The bug described in comment 0 does not occur ox X11 too. Noticed another bug on Wayland: 1. start Wayland session 2. open Konsole or another KDE app 3. right-click on the app icon in the window decoration: the context menu opens as expected 4. open any app mentioned in the step 3 of comment 0 and maximize its window 5. right-click on the app icon in the window decoration: nothing happens 6. alt+tab to Konsole and right-click on the icon in the window decoration again: nothing happens this time
