Hi,

Originally I thought that it is only irrlichtNx problem, now I believe it is more on the original code and assumption made in irrlicht, may I ask if my findings may have some fixes ?

as i posted in the NX forum, this is probably a problem with 32 bit back buffers that have an alpha channel. the alpha channel of the format should be changed to an ignored channel (change the A8 to an X8 ).

from what ive read in the dx8 docs, back buffers ignore the alpha channel. this might be different in dx9
