Hi Salvation,

Thanks for reporting, enabling the alpha channel should fix this.

Cheers
Chris.

hi
in the new bet303 release the fireflies are gone but now in the other channels, the edges are hard aliased.
if i enable alphachannel all is fine
-> in the previous release the edges were antialiased (smooth)
-> is this a new bug or wanted?

That is wanted, because antialiasing changes the color at the edges and with that the values that are represented at the edge.

With an alpha channel edges appear smooth, but that's only, because the alpha channel makes edges fade out smoothly, while the actual RGB values are still non-antialiased.
