Is this related to improperly expanding the jpeg to 32 bit, and possibly
corrupting the alpha channel?

It's related to jpegs. When I grab your jpg, it displays striped as
well. When I save it as tga though it works fine.

Yes, pretty much all of our system textures are failing (they
are mostly JPEGs). If the trans value is set below 0.5 then it just
turns grey. At 0.5 it renders, but not much more transparent than our
radiant and it has stripes. So it's either loading the image wrong,
which I doubt since it is correct in the texture window, or (more
likely) rendering it with odd blending. The images themselves do not
have alpha, we're just using the trans X setting on the shaders.
The msg below refers to textures\system\trigger.jpg

The texture file loading and the camera drawing code are pretty
different
in GtkR. But transparency should be working fine though. I think
it can be
done with both a shader parameter or alpha channel in the
texture (.tga).
Not sure this is working with png (you're using png, right?)
Can you give us some of the textures that are problematic? I
suppose those
are editor utility textures? Such as clip etc.?
