In Photoshop CS4 tryout in Mac OS X 10.5.5: Selection marquee is incorrectly drawn one pixel to the left of the actual selection. Simply create a new document, like 800 x 600 pixels, then select all (Command+A). The "marching ants" selection marquee is shifted one pixel to the left of where it should be. Can anyone confirm?

I’m unsure how to report this to Adobe. They don’t make it very easy.

Aaron,

They don’t make it very easy.

Just click on either of the "Contact" links, which appear on every forum page (both top and bottom) and then click on "Feedback".

Well, since it appears as if a pixel is being split by a marquee selection, and since by definition a pixel cannot be divided, then it’s a display anomaly.

What you’ll have to figure out is what region the marquee actually defines when you see what appears to be a line of marching ants running through the center of a pixel. Does the "partial" pixel end up inside or outside of the selection?

Then again, depending on the type of work being done, it may not really matter much, from a visual standpoint.

It may be off slightly depending on the video card and driver version used. It’s a video driver bug.

Where did you obtain such an animal? To my knowledge, Adobe has not released a demo of CS4 yet.

Ramón:

Some selected people may have received pre-release "Evaluation" copies of CS4 from Adobe which they are running in Trial Mode.

That has happened in the past.

Without an NDA? No wonder cracked/hacked copies of CS4 are all over the net already.

I do have the same problem. at 100% the selection looks like it’s shifted one pixel to the right. And it looks like it’s has selected the canvas border. I am running Photoshop on G5 with 10.4.11.

This bug still persists in the real release version. The marching ants selection box draws 1 pixel to the right of the cross hairs curser. CS3 did not have this problem. It’s most annoying along the left edge of the document where a "Select-All" looks like it’s missing the very left column of pixels.

Platform: Mac – Dual-Core Intel Xeon
Video Card: NVIDIA GeForce 7300 GT

The 7300 GT card is not on the "Approved" list for using Open GL in CS4.

Do you still have the same problem if you disable Open GL?

This problem doesn’t occur on a G5 with a nVidea 7800GT card running CS4 on OSX 10.4.11.

I have the 7300 GT card running 10.4.11 on a MacPro and I can verify that turning off Open GL solves the problem. So we either have to get a new video card or live with it I suppose. I seriously doubt if the 7300 drivers will be updated.

Kevin – that is due to the OpenGL drawing in CS4, and is a bug in the video card driver. They’re working on it (but have bigger bugs to fix first)

I have a G5 with NVidia 6600 LE video card running on OS X 10.4.11. I am experiencing the same problem and turning OpenGL off solves the issue so I guess more than one videocard is affected by this.

For the sake thoroughness, I posted about experiencing the issue, but I’m not in a position to submit a bug report because my entire system not officially supported, not just the card.
