I'm tired of that PINK HORROR and that's why i still use one of the 2014 Magic Lantern Build.
I've asked that same question but no one has yet answered the question.
Now we are two people i believe asking ALEX;
ALEX please answer us?

I am another one to report pink frames with global draw turned on.

5D3, trying both 1.1.3 and 1.2.3 and pink frames appear mainly when shooting 50fps.

[a1ex]

Steps to reproduce, please.

I've ran some tests with MLV for about 45 minutes, trying to push it beyond limits (30/60fps, 3.5K, magic zoom or focus peaking while recording), but could not get a single pink frame or crash.

Just started with MLV on the 7D (6D works, no problems) and I see exactly the same as in the OP's video. What information is needed to find the source of this problem?

[Walter Schulz]

Settings used would be a good start. And card's specs and benchmark results.

43,6 MByte/s write rate required. Too close to the edge for this card IMO. Try lower data rate or faster card.

[sgofferj]

Will do. I also noticed something funny... When I connect an external monitor, I have dropped frames after a few secs. Without external monitor I don't. I can consistently reproduce that.
Edit: Is there an interface speed limit on the 7D like on the 6D? Or does it make sense to buy the fastest card I can find?

Will since everyone being posting comments Off topic that has nothing to do with the OP's 5D2 problem .
 I try and help , One of the problems is Slow Card Write speed that produces corruption this can happen in 3Xcrop mode or 1:1
What are your Camera setting ? CF Card Speed & did you benchmark your card for stable speed.
What's the frame rate , did you use Frame over ride to lock the fps ?
What was the original frame resolution ?
FYI: 3xCrop mode defaults to 29.97 unless you use frame over ride to lock it to the 1:1 mode no mater if it's 24p or 25p
The 5D2 is limited about 79MB/s write speed  for short bust of about 500-600 frame , for continuous 100% duty cycle
72-74MB/s is the limit .
Reason I mention the frame rate I notice in the original Vimeo file it say 25fps and if you use a high frame resolution
you can get corruption like that. 5D2 is really limited to 23.976p @ 2048x872 (MLV) or 2048x930(.Raw ver1) in 3XCrop mode.
This is from my experiences with my 5D2 on ML for nearly 3 Years.
So I have seen this before many times , minimum CF card specification is 1000x for stable magic lantern.

Thanks for you replies

I'm using a Kingston 800x Cf card and shooting at 30fps in 3x crop mode , I can get stable results at 1312x710 with no pick flashes or dropped frames , which is about 50mb/s. If i go for a fast card say a 1000x or 1066x could i push the resolution up to nearer HD because 1312 seems to be my max..

Thanks

sorry for the late reply

Yes if you get some 1000x or 1066x CF cards , but Not at 30 FPS  24 or 25 FPS is the limit for stable ML raw @ HD or near HD
& in 3x Crop mode you will get 2k plus audio.
My 5D2 is my Money Tree ! I use it professionally @ 23.976 1856x928 (scales very nicely to Full HD 1080p) & 2k (2048x872)

You still can record @ 30p (but why would you , 30p is too digital looking IMO) at smaller frames , I think the last time I tried
with mlv I got 1600x800
