So this occurred on the steam version of the MCC, When I went to customize my spartan in the customization tab, the character model was zoomed out, and the bottom half looked expanded like the edge of your screen looks when you have a high FOV. Every time I selected a part of the spartan’s armor, it would zoom in a little bit like it was supposed to, but when I exit out of that particular piece of armor the model would just get smaller and smaller. Soon it was so small it was only made up of a group of pixels on my monitor. This happened with every game’s character icon in the customization tab. Luckily, exiting the game a going back in fixes it, but it was such a weird bug that i thought it was worth pointing out. Has anyone else had the same thing happen to them?
Might be worth filing a bug report about this on the Halo Support site: https://aka.ms/HaloSupport
