[color=#333399]Update: Fixed in 4.0-9113[/color]
I've been reading about the water effects on some wikis but I can't find them now, I have also been searching the forums for threads about it but I found nothing, so, although I'm aware this is a known issue, I'm starting a new thread about it. I took the screenshots using 4.0-4833. This was always present in OpenGL in older builds but it hasn't been fixed yet. I noticed that "tartan" patterns appear when water surface is displayed, not letting anything under it (or behind it) be visible. This issue is in more than one games, I'm using Super Mario Sunshine and Sonic Colors as examples.
While in Super Mario Sunshine it's not a major problem because once Mario decents, everything underwater is visible with the effect remaining on the surface only...

... in Sonic Colors it makes gameplay much more difficult, because in some multiplayer levels containing water, the surface effect is normally used around cubes of water, which were placed one next to another in there to create the stage.

Note that nothing is visible underwater, not even the player(s), or springs & switches, or enemies, or other hazards.
  In an other topic someone said that those effects (such as the sun in Paper Mario TTYD) are dual core issues and are fixed by either using single core, or fake-completion determimistic dual core. I've tried both. It isn't fixed with single core. The game crashes before it even opens if I use fake-completion. I've also tried other settings combinations like EFB to Ram with and without texture cache but nothing changed. I know that this is an OpenGL only issue and doesn't appear using Direct3D, but I'm now using the Mac version of Dolphin.

Intel driver issues, now if they are cross platform i don't know but i never experienced it with my nvidia card.

No, just Mac drivers. I have the intel HD 4600 (pretty close to the Iris graphics the OP has) on Windows, and it plays fine for me in OpenGL.

When I used to play on Windows, the graphics card was NVIDIA 9400M (very old, but still, not Intel) and there was the same thing on water surfaces.
EDIT: That was true when I was using 4.0-1xxx builds. I noticed now that it happens only on OS X. So, yes maybe Mac drivers are different and they handle OpenGL differently in some cases...
