Your not the only ones to have this issue and its really annoying. It happens to both the zibo mod and ixeg but not with default planes. If you switch to free camera mode and move the cam around the plane, it seems to occur in a specific area in and around the outside of the aircraft. Its Vulkan related but also linked to ad on planes and there interaction with SMP.
I would love someone to find a fix for this as it ruins my zibo fights with Vulkan.
