[news.eclipse.platform.swt] Problem with plugin swt opengl 3.1 on linux

[savone_davide@xxxxxxxxx (Davide)]

HI, 
I'm developing a plugin that uses swt opengl plugin. I have developed it 
on windows. Now I'm trying it on Linux and I have a problem with the A 
parameter on RGBA color. I have set the init to work with solid appearance 
but the object appear trasparent. 
What can I do ?
Thank you for all.
Davide.
