Mageia-7 32bit very slow wallpaper window management

[mirej]

Mageia-7 i586 5.3.6-desktop-2.mga7
Very slow operation in the desktop wallpaper management window. Opening the window slows down the toolbar menu.
After closing the desktop wallpaper management window, the system works quickly.

Qt Version: 5.12.2

I have faced the same problem in many distros with KDE.

Very high CPU usage, in some KDE System settings sections.

The only thing I have found (long time ago) was to configure it to "Icon view" ─ never "Sidebar view", since it was added ─ maybe, because my hardware is very old and low-end.

Doing so, I have reduced the problem just to some sections.

I don't know how to solve it. I am just avoiding to deal with this. Using the same Wallpaper for a long time.

Hello
Do you know what command Launches the desktop management window from the console? I want to see what is causing the slow down. Processor when changing the wallpaper first-core 100% load by plasmashell, second-core 15%
