Note this is probably not acceptable report either, since issue happens only with OpenCL and enabled transparent shadows if I have understood correctly?

"Bug happens with both x64 and x32 official versions at factory defaults" so no, not modified.

I know you have a lot of bug to deal with, but it takes lot of time to find bug and make simple file. Getting many real bugs as incomplete, even when I really take care of my wording ( I'm no native english speaker but "official" means not modified) is really annoying because most of the time, those bugs are forgotten for a long time. So please read carefully or at least let a chance for 24 hours to your testing community to respond to your question before marking as incomplete.

"Incomplete" means the issue was reviewed by a developer and some action is required from reporter's side, it doesn't mean the but report is wrong or so.

And just to be sure, is 15.5 version you're using dated by 5/28/2015 (as in, current latest Beta version) ?

The driver installer is named with 05/27 and windows says 05/26. To be sure, driver version is 14.502.1014.1001.
Sorry for the misunderstanding Bastien, I thought it means the bug reporter didn't do his job correctly.

2.75.1 05b2ab1 doesn't have the bug anymore. Still, on 2.75RC1 it's reproducible every time.
