Hi,
I have a strange bug which appear only with FB Alpha SVN core (0.2.97.38) and with Psikyo games (Gunbird 1 & 2, Dragon Blaze).
With FB Alpha , there is no problem.
I am on the last stable build , windows x64.
See attached file :
Its not related to shaders (I tried with crt geom and Royale Kurozumi)
