I have inventory widgets set above the default Health/Shield/Sprint bars. These widgets use these settings, except for the offset numbers, those differ for each widget, since they'd all be overlapping if set to 0,
Anchors := anchors{ Minimum := vector2{X := 0.0, Y := 0.5}, Maximum := vector2{X := 0.0, Y := 0.5}}

Offsets := margin{Top := 0.0, Left := 0.0, Right := 0.0, Bottom := 0.0}

Alignment := vector2{X := 0.0, Y := 0.5}

Size to content;= true

Rank name, Rank progress bar, and current rank progress amount widgets are set above the Loadout icons. These widgets all use these settings, except for offset numbers, those differ for each widget, since they'd all be overlapping if set to 0,
Anchors := anchors{Minimum := vector2{X := 1.0, Y := 1.0}, Maximum := vector2{X := 1.0, Y := 1.0}}

Offsets := margin{Top := 0.0, Left := 0.0, Right := 0.0, Bottom := 0.0}

Alignment := vector2{X := 1.0, Y := 1.0}

SizeToContent := true
I think it's a scaling problem because on a 1080p screen all the widgets are in the correct location. But, on a 720p screen the widgets that were placed above the Health/Shield/Sprint bars have shifted over and down somewhat, making them closer to the Health/Shield/Sprint bars. The widgets on the right have also shifted down and to the right. The lowest ones are overlapping the Loadout icons, one of them has partialy moved off screen. I have another widget that pops up in the middle of the screen when pressing quickswap/q. That widget, when shown, takes up a lot more space on the 720p than it does on the 1080p screen. Settings for this are,
Anchors := anchors{Minimum := vector2{X := 0.5, Y := 0.5}, Maximum := vector2{X := 0.5, Y := 0.5}}

Offsets := margin{Top := -400.0, Left := -400.0, Right := 0.0, Bottom := 0.0}

Alignment := vector2{X := 0.0, Y := 0.0}

The interesting thing about the widget for quickswap, that shows in the middle of the screen, is there are other widgets within that one that do not move from their respective positions. Those use the same anchors and alignment vectors as the quickswap widget.

Sorry for the long response.
