Hehe, yes Lele it is a bit odd. Here is the image so you can see for yourself https://www.dropbox.com/s/cr2w1nzgo6...PHA.vrimg?dl=0

Oh, the alpha itself when affect channels is active.
Yeah, that's OK-ish, alpha can be clamped without much issue in this case.
I thought you meant the refraction filter was higher than 1.0, sorry.

the example with a car window - ray hits curved glass, gets redirected and hits environment.

will VRayAlpha support on GPU make it into official 6 release?

This should work better than V5, there are handful of cases logged that will be addressed including Render Elements behind glass.
This topic is still high priority on the GPU roadmap, I don't have a timeline when this will be addressed. After 6.0 is released it should be more appropriate to tell

Best,
Muhammed

This was the main reason I dropped GPU rendering. I couldn't render a car beauty with the windscreen on...the examples provided look correct now, from what I can tell.
