It happens with all exo suits, spacesuits, firesuits, whatever. And iirc only for the front/back views. Facing to a side shows your backpack correctly.
Another hand bug. Hands are drawn above every layer, take a chair in your hands and you'll see a pink hand sprite floating above the chair. Gloves are the only overlay drawn above hands.
This partially covers many of in-hand sprites. For instance, syringes look a lot like pens, toolboxes are half covered.
Two other annoying things that has been around for a while, is that when wearing a genetics lab coat, and facing left or right, your whole arm becomes invisible, and when wearing most types of shoes and lying down, the left shoes turns invisible, showing just your foot.
