NES games don't render on OS X

Fixed in 4.0-9113
If I try to play a NES game on OS X, it shows this picture. [Image: gwUtyOs.png]

No matter what changes in graphics settings I make, the issue persists. This same picture appears in all the NES games I have (Super Mario Bros, SMB: The Lost Levels and SMB 2). It seems like another "bad driver" issue, as people say. It's only the video that's problematic, audio and input work fine. This happens with NES games ONLY. Other console games render normally and I'm talking about Sega Master System, Sega Mega Drive/Genesis, Turbografx16, SNES and N64 games. Sonic & Knuckles also renders perfectly, even though there were some builds that it did, later it didn't and now it does again.
I tested using the 4.0-8863 build. The reasons I report this now and not before are:
• I've search and I didn't find any similar threads
• In the January progress report, we are asked to report bugs, before 5.0 stable is released.
However, there's a chance this is impossible to fix, such as other rendering issues that I've encountered on OS X, such as Stereoscoping 3D not working (https://forums.dolphin-emu.org/Thread-does-stereoscopic-3d-work-on-os-x), water surfaces not rendering properly (https://forums.dolphin-emu.org/Thread-opengl-water-effects).

I noticed that the above screenshot shows the same thing as a screenshot in the second link I gave above.
Compare it with this:

Isn't it the same pattern repeated over and over?

This is most likely the same problem as the water. This used to be treated as an unfixable problem with OS X Intel graphics drivers, but the problem is actually being worked on now: https://github.com/dolphin-emu/dolphin/pull/3570

Glad to hear that!
Wait! So, it happens only with Intel iGPUs? I thought it happened because OS X doesn't support OpenGL newer than 4.1. Guess I was wrong!

Yeah, OSX has generally awful drivers for Intel iGPU.

Sorry to revive this, but I just did some testing and confirmed that this issue was indeed fixed as of 4.0-9113. I also updated the first post here, mentioning the fix.
