dragging mint.Window = massive lag (Windows 10)

It works fine if I target web, but if I target windows I get this:

Interestingly, if I record it with ScreenToGif, it's much less stuttery and I get this:

I've fixed it. The problem arose from this bit of code :

 var label = new mint.Label(...);
ed_controls.add_item(label, 0, 8);
list.size(label, width, 100);

but if I changed it to :

 var label = new mint.Label(...);
layout.size(label, width, 100);
list.add_item(label, 0, 8);

It now works. There's still an underlying bit of weirdness happening underneath which I don't understand, but it should be addressed. This only happens for the cpp build.

Scratch that last comment. I still have this problem with windows if they're heavily populated. I've attached a hxScout telemetry file.

Just curious if you're testing in debug or release when you're seeing this? In debug it will definitely be far more pronounced. The layouts aren't optimized or anything they're doing the most obvious stuff right now, so if you had a whole bunch of them updating when the window moves, it's possible that they're triggering themselves more than once or other things. I'll look into it but the idea is to implement the constraint system, margins is a simpler convenience in the mean time.
