Hi all,

It was hard to place this in the correct section as it could be a Kwin issue, but its also under appearance anyway, I originally thought this was a problem with a style script engine "Kvantum" however it appears the problem occurs without it also. It happens on several themes from different authors so I think it comes down to something KDE.

Everything works well if I use default Breeze-Dark, but as soon as I switch to a theme listed in the KDE store (tried 3 from 2 different authors), some windows from dolphin and Ark (usually dialog windows) will appear at screen position 0,0. Why is this a problem? Well, I have 2 different resolution screens, one atop the other due to space, and the smaller screen is on the top. Hence position 0,0 is located off visible screen. I temporarily moved the top screen in system to the right, making 0,0 on the top left of the main screen, and sure enough the dialog windows appeared at that point. It happens with the folder properties window in dolphin, but file properties window appears in the correct position?

I have tried making a rule in the window rules to position the windows at the center of the main screen, I have tried checking both and alternating the window behavior "active screen follows mouse" and "separate screen focus" and still these windows appear at 0,0.

Themes I have tested with: Ant-Dark, Sweet-KDE and Aritim-Dark - each with the same problem

KDE plasma version 5.21.4
QT version 5.15.2
Arch linux 5.11.16
