Emulator

Do you have any kind of antialiasing enabled? If so, then this bug is likely the same as on windows.

Can you give us a screenshot of the game window filled with garbage?

Ok can I upload a small screenshot on this page ?

Here are 2 screenshots of Dolphin-4350 (which enables Stereoscopic 3D) on my iMac 21" with ATI Radeon 4670. Note that the application "OpenGL Extensions Viewer" OpenGL tests all works properly (with Anisotropy ON) up to OpenGL 3.3

The latest build Dolphin 4.0-4473 has also the same issue as Dolphin 4.0-4350, even with every "Enhancements" or "Hacks" turned OFF or ON :-(

Are you sure Anti-Aliasing is disabled? (Set to 1x)

Do you have this problem with every game you play or just a few?

Yeah right same issue on every game (Wii or Gamecube) since Stereoscopic 3D support...also with or without Anti-Aliasing set to "NONE". I tried everything possible in the Graphics Config dialog.

Ok, then this is most likely just a general incompatibility with layered textures.

Please try this build: http://dl.dolphin-emu.org/prs/pr-1651-dolphin-latest.dmg

@Jules how did you provide a OSX build if it failed in github?

Yes! Thanks Jules.B!! it works with Anti-Aliasing set to NONE, however with Anti-Aliasing to "2" or higher I get a garbaged game window. Setting it back to "NONE" while the game is running the game window switches from garbage to normal...
Thanks for your effort.

Ok thanks for the description of the issue...Ok I'm waiting and will let you know

Please test the latest build: http://dl.dolphin-emu.org/prs/pr-1651-dolphin-latest.dmg

The PR is ready to merge. If everything went well, this build should behave the same as the previous one.

I just made another change to the that build, Anti-Aliasing should also work correctly. It was unrelated to blitting after all.

Hmm...your latest build (from comment #13) has again garbage !! I tried with differen Anti-Aliasing settings but no go.
But as I reported the build from comment #8 works, but only with Anti-Aliasing to NONE...

Can you try it again? I think you downloaded a build that still has an error.

I just tried again..it seems to be the same build, the DMG is from time 21:03...still has garbage
http://dl.dolphin-emu.org/prs/pr-1651-dolphin-latest.dmg

Ok, but it still works as long as Anti-Aliasing is off right?

No still garbage, even with AA to "NONE"...the one who works with AA to "NONE" is the build from comment #8

This is very strange, as there should be no functional difference between the two. Please try the latest build: http://dl.dolphin-emu.org/prs/pr-1651-dolphin-latest.dmg

Sounds crazy and strange, but your latest dolphin build from comment #20 has still garbage at any AA settjngs...

Please try the latest build: http://dl.dolphin-emu.org/prs/pr-1651-dolphin-latest.dmg

YEAH! Ok the build from #22 works! But only with AA set to "NONE"...all other AA settings gives garbage...

One more build: http://dl.dolphin-emu.org/prs/pr-1651-dolphin-latest.dmg

I'll move to merge that one and I'll try to fix AA on your GPU in a later PR. It's probably the framebuffer blit after all.

Tried the build of #24: works, but only for AA set to "NONE", all other AA settings renders garbage!
Thanks again for your effort.

I think the best option is to not support AA on graphics cards that don't have their shit together :P

I set AA mostly to NONE to get the best performance ;-)

@JMC4789

The problem will probably be fixed by supporting MSAA with stereoscopic 3D, it'll be a two birds with one stone situation.

Oh, that's excellent! That works for everyone, then.

Try this build, it has been merged and may fix AA for you: https://dolphin-emu.org/download/dev/a381d25d7680f393dd9d34fc2df80ffc42cc4597/

Thanks all! I just tested again and it the games works again, but ONLY with Anti-Aliasing set to "NONE"...all other AA settings renders garbage. But I don't mind, since most of the time I'm not using AA ;-)
Thanks all!

Yeah, the AA will probably get fixed by something else; I wouldn't worry about it too much!
