Sometimes, when you jump with first person legs on, your waist and neck items block the screen. I’ve been having this problem since 0.7.0.0 (when the first person legs option was added) but I kept forgetting to report it until now.
(the screenshot was taken in 0.8.3.0 but it still happens in 0.8.6.0)
It only happens sometimes and is only on the screen for a frame but it’s still a bit annoying.
