Addons fail to stay in place after PiP swap

One of the few questions I can't find a decent answer on,
maybe I overlooked something.
I hope you can understand what I'm trying to describe.

I've been trying to get a UI compilation going,
It was a painfull, timeconsuming, yet educational experience.

But now that I'm done:
As soon as I make another window my main with PiP it doesn't resize the addons decently and some bars end up on different positions.
At first if i swapped my clone to my main and back the bars would end up more towards the middle of the screen.
I expect screen clamping of most mods made this happen,
but then I turned the clamping off and now some bars are ending up almost offscreen.

They all have the same resolution in maximizer 1280x1024
My main window is 1280x1024 and the clones are 640x512

I didn't have this problem before I rearranged my windows and started on the compilation.
They had the same resolution in maximizer,
but the clones had a 320x256 resolution.

I've got the feeling it has something to do with the ratios,

but I just can't grasp what it is.

[EDIT:] already reverted back to my old settings and started adapting again from there. Backups ftw \o/
