Ghost images after rotation of a group when export in JPG

[régisg73707670]

Hello,
When I export JPEG or PNG or "save for web (legacy)", I have some rectangle that appear on my image, and they are not in Photoshop.

I have created this image, with a comp card  (a group of layers), then I have rotated the group of the comp card.

In photoshop (print screen):

If I export as JPEG or PNG

If I export "Save for WEB (Legacy)

Do you know this problem?
Is it a workarround existing?

Thank you in advance for your help.

Could you please post a screenshot taken at View > 100% with the pertinent Panels (Layers, Channels, Options Bar, …) visible? 

Does turning off »Use Graphics Processor« in the Performance Preferences (Photoshop > Preferences > Performance > Graphic Processor Settings) and restarting Photoshop have any bearing on the issue?

Hello,

Thank you for your reply.
I will try it.

I was a bit tired the other day, so I couldn't search.

I suppose that is coming from the shadow applied before rotating the group.
I unset all the layer to identify from which it's coming, see the print screen.

The view of Photoshop:

Result after "Save as JPEG":

I did the change in the preferences.
I restarted Photoshop.

No improvement.

As I was supposing, the problem is created by the "Drop shadow":

In Photoshop, Drop shadow unactivated:

Save as JPEG

The problem is not there anymore:

My settings for the Drop Shadow

I will try to delete it and recreate it with same settings.

[régisg73707670]

I deleted the effect.
I recreated it.

I set the same settings.
Same problem.

I change settings, like angle, layer Knock ... or anti-aliased.
Same issue

I thought it was coming from the "Drop shadow", but not.

When I remove it, the background is white in JPEG, so the ghost white rectangle is not visible, but he is here.
I discover it because I replaced the "Drop shadow" by another layer with a black rectangle + gaussian blur.

So I added a solid color layer (Red)

And we can see clearly, that's coming from my simple rectangle that got a rotation in the group.
But I really have no explanation.

I forgot to attach the JPEG:

Problem still here.

[régisg73707670]

I think the problem was coming from the fact my big white rectangle was on a "filled layer" (I don't know what that mean). But it looks like a BUG.

My workarround:
1) unshow all layers except the one of my big white rectagle. select its layer.

2) I have selected my big white rectangle with "Quick selection tool"

3) Edit > Copy Merged

4) In a new layer: Paste Special > Paste in place

My new layer doesn't look like the original one. The original one has a small kind of rectangle in the corner.

And the result is good now:

What is the exact Photoshop version? 

So far I could not reproduce the issue, but the important thing is you found a work-around. 

[régisg73707670]

Hello,

The version is the last one: Adobe Photoshop Version: 22.1.0 20201125.r.94 2020/11/25

at least, it says that i'm up2date.

It will be good if I can give the file to adobe, to fix the bug.

If you can reproduce the issue reliably please post a report over on 

Photoshop Family

that’s the official and monitored place for Photoshop Bug Reports.

Happy new year
