I still check this every few days for news. I understand the developers have many issues to deal with, but could someone please commit a simple fix for this problem? It's the only reason why I can't safely use shaders in Second Life, Stuntrally, and potentially other engines... for about two years since the issue was introduced here. I confirmed a line in the code which fixes the problem, as well as the commit which introduced it, thanks to the suggestions in the comments above... so hopefully a solution isn't that difficult now. Any thoughts please?
