Two bugs that I did spot recently...
Ki-27 Ko and Otsu
Part of the engine cowling appears in the gunsight and is clipped.
Ki-43-Ia/Ki-43-Ib/Ki-43-Ic
The prop disc appears to intersect with the camera at times creating some clipping. It's particularly irritating when at full throttle as the flickering does get intense.
Apparently not all can see this. I'm running at a customized 1920x1200 resolution. SaveAspect is set to 0. Not sure if that may be relevant.
