Seams between polygon edges

Hello,

I was testing cube 2 on my ATI x800 and I noticed that background is leaking thru the polygon edges of everything if you are inside... If I enable bloom, it's even worse as it becomes brighter...

Is there any way to fix it? Any ideas will be welcome, I can even code it myself, but need an idea how to fix it.

Thank you!

Seams/sparkles - I believe it's an issue of T-junctions, and I'm not sure if a cheap algorithm exists to adequately decompose the cube geometry into a nice T-junction free soup of triangles... otherwise I'm sure eihrul would have imlemented it by now ;-)

'sparklies' as they are called.

The engine has a 'sparklyfix' variable, but apparently it wasn't working properly. I've been told this has been fixed in CVS.

Other useful things you can do is use a dark skybox (eg. "skyboxes/black"), and on ATI cards the 'ati_skybox_bug' helps remove the distortion/leaks.
