Images distort while editing

I too have this problem since installing SL and it's REALLY annoying!

iPhoto, Preview, and Aperture are all affected.

I'm running an old Intel MPB with an ATI card. Come on Apple, get this fixed!

Another 'Me too' I'm afraid, MacBook Pro 2.16 10.6.2 Radeon X1600 with external monitor. Sometimes using the 'shift' key repeatedly might make one picture show correctly, but most of the time it's that darn distortion.

Please send your feedbacks to Apple, I just did that and that is the only way to let them know about this bug!

Don't forgot to mention this also affects Aperture and Preview too.

Have the same problem after installing snow leopard, leopard worked fine with i photo 09 until i downloaded snow leopard.
Hope apple come up with a fix soon.

Add another "me too!" to the list. I have entered a bug report, but have had this issue ever since updating to SL a few months back.

I really hope a solution comes out soon!

Count me in too. Same problem on my iMac CD with ATI card since my upgrade to Snow Leopard. Sent a bug report to Apple yesterday. I made a clone of my iMac´s hard drive to an external HD and started my macBook Pro with that disk. No more distortion on my pics. Since it´s the same iPhoto library as on my iMac, it seems to be related to the hardware, i.e. the graphics card/driver.

Apple, please help!!!

Yep. I did this. Hope Apple will do something about the issue, since other users reported the error before and nothing happened.

As mentioned above by smiff, pressing the shift key might help, but you will see only the unedited image.

"As mentioned above by smiff, pressing the shift key might help, but you will see only the unedited image."

Not for me, sometimes the distortion disappears from the edited image. The same sometimes occurs when continually dragging sliders, though this is less frequently true.

Still having this problem. Does anyone have a solution yet??

I have exactly the same problem (images become distorted while in full screen editing mode, just like the posted screen shot in the first post).

It started since I upgraded from Leopard to Snow Leopard, using iPhoto 09 (8.1.1). I tried reinstalling iPhoto and the iLife Support 903 update, but the problem persists.

This issue has clearly been caused by the 10.6 upgrade, I never had anything like this before.

Just downloaded the Aperture 3 trial, imported two images and got the same editing problem mentioned here. Maybe Apple will fix the problem now!!?

I'm also seeing this in Aperture 3. Even worse. I can't seem to do any editing at all in Aperture without this issue popping up. It is such a pain.

I've been having the same problems for months. I cannot show friends my photos as a slide show anymore because do many images - especially edited ones (particularly those with highlight or shadow compensation) just degenerate to red/green fuzz with a diagonal stripe.

Seems like later models (with Nvidia graphics) do not suffer with this problem, so perhaps Apple is sitting-back and waiting for the problem to subside. Not very responsible really given what we paid for our hardware and the fact that it is still perfectly capable in almost every other respect.

I wait in hope that a solution may yet be found.
