Patch rendering

[James C. W. <jfc...@ya...>]

So I've got a potential bug relating to layered patch rendering...

  I've got a slide node with a
blank, opaque background. Over the background there are two patches: One, is a
wider-then-background image which scrolls back and forth over the background.
The second, is a PNG with a part in the middle made transparent, so you can see
the scrolling image behind it. It all works fine, however, I can see a seam,
one pixel wide, running on the left and right edges of the patch, peeking down
onto the scrolling image and the opaque background.

    This seam is also present in
another node where the patch underneath is smaller then the background and not
scrollling.

    If the cause of this is well
known I'd appreciate a heads-up. I've already checked the PNG to see if I
accidently created this seam myself while editing; that wasn't the case.

 

 Thanks,
