Scrolling through the 10 slots while in ship mode doesn't work well for me. It if scroll upwards "fast" (so to the right of the hotbar), it seems to not update instantly and lag behind or jump back to the left of the hotbar. It's an annoying issue during combat since I have to scroll slowly to make sure I don't select the wrong weapon.
I don't have this in build or astronaut mode however.
I'm using a logitech G500 mouse. driver: 8.45.35.0
