Opening the wallpaper GHNS window locks everything on the desktop until it's closed again
STEPS TO REPRODUCE
1. Open "Configure Desktop and Wallpaper..."
2. Click "Get New Wallpapers..."
3. Try to do anything on the desktop, e.g. open context menu, desktop icons, etc.
You are unable to do anything with the desktop until GHNS is closed again
You can still interact with the desktop
OS: Neon Testing Edition
KDE Plasma Version: 5.22.90
KDE Frameworks Version: 5.87.0
Qt Version: 5.15.3
It affects the most when it is open on another virtual desktop, since you will not find the blocking window in the taskbar. The same happens with the wallpaper plugins GHNS window.
This happens because it's marked as a modal dialog, and modal dialogs block their parent app until closed. When the parent app is Plasma, Plasma gets blocked while it's open.
- Make it not be a modal dialog
- Make the modality of the dialog configurable and have Plasma open it in a non-modal way
This bug appears to be fixed now (Plasma 5.24.3, Frameworks 5.91). Since GHNS won't even be a dialog, but a window, from Frameworks 5.93 and onward, I feel confident that this bug is past us for good – even if I can't pin-point exactly when it got fixed. Thanks devs!
You are correct about all of that! The exact commit was https://invent.kde.org/frameworks/knewstuff/-/commit/ea19fa6e824650f3257e8047d6f90e01899b2e03, made by Alexander Lohnau.
