OpenGL TTriSurfaceSeries transparency Bug

[Ael]

Hello,

I have recently installed Delphi XE2 and TeeChart 2011 for RAD XE2 and i have a bug with TTriSurfaceSeries with TeeOpenGL rendering.
if i activate transparency into this serie, only the last drawn triangle is transparent.

See attachment for screenshot.

Before i was under Delphi 2010 with Teechart 2011 for Deplhi 2010 and i hadn't this bug. but i can't use it anymore.

if someone just help me solve this proplem or circumvent it...

Hello,

I could reproduce the problem so I've added it to the defect list to be fixed in future releases (TV52015900).
I'm afraid I can't think on a workaround for this right now rather than using GDI+ in the meanwhile, if possible.
