[Bug 93648] Random lines being rendered when playing Dolphin (geometry shaders related, w/ apitrace)

https://bugs.freedesktop.org/show_bug.cgi?id=93648

--- Comment #6 from Nicolai Hähnle nhaehnle@gmail.com --- Found the bug: we didn't properly update a piece of state in a specific (but not all that unusual) sequence of operations involving geometry shaders.

I have a preliminary series containing the fix at http://cgit.freedesktop.org/~nh/mesa/log/?h=shader-state

I remember that you mentioned other rendering bugs in Dolphin that showed up using your automated tests, but I don't think you've filed bug reports for them. Of course they may well have had the same root cause, but if any of them persist after the fix for this bug, I appreciate similarly high quality bug reports in the future :)
