It appears the in Game panels are not following CSS as it does in PC, causing distortion in the game panel design.
Repro steps:
Load FSR300E on Xbox, open the ingame panel to control the FBOs (top panel, FSR Logo), inject 1 FBO (click on the map, inject a building anywhere), select the building, and see the options render, sliders, etc.
@Boris but if you extend the panel (drag it on the border) you can see on PC everything fits and works, people can extend / shrinks the panels dinamically..
