I have been seeing weird behavior in iPhoto and Aperture when editing photos. This is happening pretty much every time I try to use certain photo tools, such as crop or straighten. Here’s some examples. I took photos of the screen with a camera, because this is too weird for a screen capture, I think.
First, select an innocent photo of a bird in iPhoto, and select the straighten tool:
Now the slightest adjustment of the straighten tool:
Here’s another manifestation using the crop tool. That weird rectangle in the upper left shouldn’t be there. Also notice the appearance of the overview thumbnail (it looks like the same junk as the photo above).
The first time I saw this, I though my photo was probably ruined, and I would have to reboot. However, I have found that the problem is only on the screen. Fortunately, the photo is not permanently affected. Usually, as soon as you exit the edit mode and look at the picture, it looks normal again.
I called Apple Tech support about this once, but didn’t really get anywhere. The problem was present under Leopard and persisted after the Snow Leopard install. I am using a 20″ iMac 2GHz Core 2 Duo.

I have a nearly three year old 20″ iMac 2.16 GHz which was upgraded last week from Leopard to Snow Leopard 10.6.2.
iPhoto was immediately corrupted so that any photo which had been edited is unstable and may appear as a weird, diagonally striped, multi coloured image, when in full screen. The actual jpeg is not damaged but the image is distorted.
As most of my 6000 photos have been edited, in order to view them without this distortion I decided to export the edited versions and reimport them at full size. They end up looking much the same but are 20% smaller.
If left unaltered these images are stable, but as soon as they are edited the weird instability recurs.
Knowing it is automatically recreated, I was advised to remove the Library cache folder com.appleiPhoto and trash it, but this has not solved anything.
This seems to be an incompatibility problem which only Apple can solve and I hope they will soon do so.
Here are some examples:

This issue has been reported to Apple, and is discussed in the Apple support forums here:

I do not intend to upgrade to the new Aperture version 3 until this problem is resolved.
