Only in overcast or heavy cloud conditions when FOV is zoomed out the clouds and gunsight disappear - they reappear when zoomed back in fully. Happens in internal and external views.
I've had this same issue when trying to film cinematics. If you use the FMB to use the heavier cloud settings they will disappear very often when looking in certain directions or with too wide a FOV. Really annoying to work around so I hope it can be looked at.
