Any DM/WM that allows for subwindow from an app to follow the main window? like krita floating tabs following the main app

im an artist whos been using arch w/ krita for a while now mainly using hyprland til i got board now ngl. i am currently looking for any DE/DM that s lightweight enough so that my intel celeron ahh can handle it and mainly ive got this problem with krita.

so i always have my color picker floating as a window and whenever i tried to move the main krita program the color picker window just says behind and that has been bothering me for a while now. especially now hyprland since its extremely finicky and buggy.

ive tried hyprland, xfce4, heck even KDE plasma the maker themself and no luck :/
yall got any recommendations? thanks a ton forward!
