Comment 1 guimarcalsilva 2021-06-24 03:45:19 UTC
I can confirm this happens, but only if the "Image" or "Slideshow" menus are selected.
Comment 2 Nate Graham 2021-07-29 15:45:55 UTC
Can confirm for the desktop settings window only when displaying the UI for one of the image wallpaper plugins.
Comment 3 Fushan Wen 2022-05-30 00:20:33 UTC
Can also reproduce in other config dialogs, so not only the wallpaper config dialog is affected.
Comment 4 Patrick Silva 2022-09-20 18:43:37 UTC
Can also reproduce with system tray settings while showing 'Entries' section.

Comment 6 Nate Graham 2024-11-05 16:49:25 UTC
This is unfortunately just the standard issue of QML window resizing being glitchy. :/ It's an issue deep in Qt.
Comment 7 Nate Graham 2024-11-15 16:22:21 UTC
...Which should be fixed by https://codereview.qt-project.org/c/qt/qtwayland/+/591892!
