UI window positions getting reset to default
 

The title. I remember UI windows remembering the last position and maintaining it, but now whenever I change a tab (for example character window go to currency tab, or switch talents) or do an operation that results in an update call for UI it will go back to the default position.

Any way to stop that from happening? I would prefer not to install another addon to fix it.

Extra: I've also noticed that UI scaler only affects infobar and not raven or buff/debuff frames. Intended behavior?

Yes i have this same problem, if i try and move anything or scale anything up, it just pops back to default.

I have a worse problem.

My Collections window decided to shirt to the right when i clicked it to move it.
I clicked to move it again and it shifted further right....off screen.

Now it only ever opens off screen if RealUI is enabled :(
