Thank you very much Michel, indeed masking this extension produces a correct trace that can be replayed to reproduce the scope bug. So here is a new apitrace showing the bug : http://dl.free.fr/oD7tgoSw9 For reference, the outside of the scope is supposed to be slightly blurred. Random screenshot found on google images to show the expected rendering : http://misc.team-aaa.com/perso_skullgun/MaJCSGO/Augscope.jpg
