Weird Scrambled images when using Intel HD Graphics

I'll also add that it does seem to be related to the Automatic Graphic Switching. In the past I have generally left it on. If a page in Safari becomes scrambled, I go to turn AGS off, and the scrambling instantly goes away. I turn it back on, and it scrambles again, and back and forth, etc. A repeatable result.

I stopped using Safari, and the problem is gone. So I assume that the problem is with Safari.

Merry Christmas!

Same issue here on my 15" i5 High-res. It's happened a few times. Went to take a screenshot today and the screenshots came out all black.

I noticed it first today when trying to use Quick Look to watch a video I had just taken off of my Canon 60D. The video was all garbled. Then Safari started going wonky again.

I opened QuickTime and all of a sudden the wonkiness went away - most likely because the computer switched to the other video card?

Grrrr.

Update, took to apple, replaced logic board. When i received the comp back it would periodically fail to boot. Took back a second time, logic board replaced again. Now video is slow/poor quality and I have continuous skips in video which is very different from when I first got my mac. Has anyone had their video card replaced? Any updates on this issue?

Same issue as described in this topic. I also add occasional complete system crashes, don't know if it's correlated.
I switched to Opera and now it works flawlessly. Let's say that Opera is bringing some regression wrt Safari. It's integration is not as seamless as Safari, especially for PDF files, download management, occasional crashes, etc. More critical, is it's resort to the NVIDIA graphical board instead of the Intel's one. I suspect more power draining with it.
It's my first entry in Mac computer world, I thought that integration between hard and soft was a strong point of this company and I'm rather disappointed, especially when I see the way Apple handles this issue.

Has anyone filed a bug report on this?

Add another Macbook to this problem list. My 2010 17" Macbook Pro has just started showing these scrambled videos and colored artifacts on the screen while running the Intel HD Graphics card in the past month. The computer isn't even a year old yet. The issue happens while running Safari with streaming videos and some flash content websites but it is hard to reproduce on command. It is easy to make it go away (temporarily) all I have to do is start Adobe Photoshop and its all better. (This is because PSCS5 causes the NVIDA card to switch on). Grab capture screen shots don't seem to work so I've just been taking pictures with my camera to show Apple. I really don't want to bother with a logic board replacement as it doesn't seem to be working for anyone else nor do I want to turn off the automatic graphics switching and run my Mac on the NVIDIA card all the time as I like have some battery life.
Will it get worse? I'd hate for my Mac to end up like my old PC whose video card died and caused the death of my laptop too.

Has Apple or anyone found a solution to this? Thanks!!

Just purchased brand new MBP 15" i5 with high res screen. EXACTLY the same issues as everyone else, glad I found this thread. Seems to happen mostly in Safari (haven't had a chance to do much else with the computer yet, it is only a month old), however it does carry over into other windows and the desktop as other users have stated. Tried to screen capture, which worked at first. However as soon as the problem went away... so did the screen captures, they turned black. Problem goes away for me eventually, but it is a annoying to have such problems on a BRAND NEW machine... calling apple soon to see what they have to say, will update with their reply.

Add another Mac user with this same problem to this list. After I first encountered this problem I googled it and found a thread talking about this same problem: http://forums.macrumors.com/showthread.php?t=959979

I then took it to Mac with the computer currently in the scrambled display and showed how I couldn't use Pages, Numbers, and other programs. They immediately told me it was the logics board and replaced it. A few days later it started all over again and noticed when I turned off the Automatic Graphics switching that the computer resolved itself. I've contacted Mac again and they told me that unless I could show them how to recreate it on the spot, there wasn't anything they could do and that I should wipe the computer and start all over. This doesn't help. The best I can do a recreating this is to open a few websites that are Flash heavy and then running Pages and Numbers to tax the graphics card.

I'm getting tired of sitting on my hands waiting for a fix and hope one comes soon.

I think that some news outlet needs to break a story about this so our voice gets heard and Apple acknowledges they are having another graphics issue. Hopefully the new processors in the yet to be released MBPs fixes this problem.

Best of luck to everyone dealing with this issue.

I have an i5 15" with this issue "screen gets scrambled, some part of the view gets frozen and stays there on top of whatever the screen is displaying, also some image parts get frozen on the desktop"
Has anyone thought about the fact it happens frequently with Safari (an Apple browser) and in the past year or so Apple was in the news because Adobe was upset that Apple did not want to support Flash any longer?
Maybe a software issue is causing a much larger problem in the Intel architecture?
Just wondering.......

Have the same issue here on a MBP 17" i7. It definitely sounds like if we take it in, they'll want to replace the logic board, which doesn't help.

So has anyone successfully downgraded Flash and had the issue go away? That's the only consistent solution I've seen (other than using the nVidia graphics all the time).

I've only tried Safari, but wondering if the issue exists in other browser programs using Flash, or if it's a combination of Flash, Safari and Intel HD graphics.

Just upgraded Flash to 10.2.152 ... going to keep an eye to see if it still occurs.

I have determined that this is a problem with the application not knowing when to successfully switch graphics cards. I have been experiencing the same problem detailed here with photos and video of scrambled screen:

http://discussions.apple.com/thread.jspa?messageID=13144734#13144734

When autoswitching (of graphics cards) is deselected then the problem desists, meaning it simply can't identify when and which card to use successfully.

No issues since I upgraded Flash. They must have fixed the bug in the latest version.

I had exactly the same problem. Macbook Pro is 4 months old now and has been doing this since nearly new. Never had the problem with my last one, which was exactly the same model - albeit 2 years older.

It's been to Apple 3 times now. First they changed the RAM, then they said it was software and wiped the whole mac, and had me reinstall the OS. Then they said it wasn't software. It was again. Then it wasn't, so they changed the logic board. You see what I'm getting at.... Everyone at Apple that's seen it has a conflicting - but very confident - opinion, so it looks like they really have no idea.

I'm going to try using Firefox instead of Safari, but the point is surely that a Mac machine should surely work properly with Mac software...
