Geometry Shaders are broken with i965 on Sandy Bridge
0%
Description
Game Name?
SSBM’s Fountain of Dream or debug mode, or any Metroid Prime, or any other game using line or point primitives.
What's the problem? Describe what went wrong.

What steps will reproduce the problem?
Launch Melee and play on Fountain of Dreams, or launch Metroid Prime and look at the minimap (press Z for the best effect).
Which versions of Dolphin did you test on? Does using an older version of Dolphin solve your issue? If yes, which versions of Dolphin used to work?
Master is broken since Armada’s work on using geometry shaders instead of OpenGL point and line primitives.
What are your PC specifications? (CPU, GPU, Operating System, more)
Sandy Bridge i3-2357 with HD3000, ArchLinux, any Mesa since 10.4 (since which GS have been implemented).
Is there any other relevant information? (e.g. logs, screenshots,
configuration files)

Upstream bug, with attached apitrace: https://bugs.freedesktop.org/show_bug.cgi?id=93418
Updated by sheepdestroyer about 8 years ago
The patch fixing the original bug has been committed to mesa master : http://cgit.freedesktop.org/mesa/mesa/commit/?id=9f2e22bf343b21d6b44e6a502f00a86d169f5ade
It has also been CCed to 11.0 and 11.1 stable trees
The next major version (should be called 11.2) and stable releases (that would be 11.1.2 and 11.0.10) should include it.
What is the plan to revert the blacklisting of the driver implemented here https://github.com/dolphin-emu/dolphin/pull/3518 ?
Updated by sheepdestroyer about 8 years ago
On Intel SNB HD 3000, built Mesa-master with included fix as well as dolphin-master with blacklist removed.
I then tried Metroid Prime and can confirm the visual bugs are not present even when looking at minimap

Mesa 11.2 has been branched 4 days ago and includes the aforementioned fix : https://cgit.freedesktop.org/mesa/mesa/log/?h=11.2

Okay. I simply don't know what went wrong. I updated Dolphin and now no matter what good version I use, all of my games have severe geometry glitches
