This one worked for me: https://github.com/Frogging-Family/wine-tkg-git/blob/master/wine-tkg-git/ wine-tkg-patches/misc/childwindow.patch
I will try the wine-tkg-git repository and build the Wine specific TKG version with Wine mainline patches, Wine staging patches and other Proton/DXVK fixes in a open container context since the childwindow.patch is included and applied for Wine version 6.20 and 6.21.
