<DIV><FONT face=Arial size=2><SPAN class=031230613-01052008>Since several weeks
there is an elusive bug in the gameengine with the rendering of alpha
faces. When the bug shows up, the alpha faces are rendered without alpha
texture, just vector color. The trouble is that the conditions of the bug are
unpredictable and variable. Typically you need to run the game twice to see it
but if you do certain actions before running the game, such as visiting some
scene, the bug may not show up at all. It depends also on the build:
I have a blend that shows the bug with RC3 for windows but not in my SVN debug
build. Interestingly, once the bug showed up in the game engine, the faces will
also be rendered badly in 3D view.</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=031230613-01052008>This indicates
a memory corruption bug that depends highly on the runtime conditions.
However, the bug is reproducable if the conditions are the
same.</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=031230613-01052008>Unfortunately, I
have not yet been able to reproduce it with a simple blend in my debug
environment. I'm pretty certain that it will be very annoying for the BGE
users if we let it go in the final release. </SPAN></FONT><FONT face=Arial
size=2><SPAN class=031230613-01052008>I just need to get a simple blend
that shows it in my debug environment and I'm sure I can fix
it quickly. Any help in getting a test blend will be appreciated.

<DIV><FONT face=Arial size=2><SPAN class=031230613-01052008>It is also possible
that the bug is related to a memory optimization patch in the BE rasterizer. I'd
like to work with the windows platform maintainer to create a build identical to
RC3 but without the patch to see if the bug disappear.</SPAN></FONT></DIV>
