P: Rendering issue with clipping layer to a group

Thanks Stefan. Looking at the issue you reference, the problem occurs with scaled UI and engineering is looking into the issue.

Thanks. The file works perfectly to demonstrate the issue. I've logged the issue for engineering to investigate.

I have uploaded a lowres version here

Jeffrey,
"PS-7735"....you know, what I mean?

Stefan, do you have a file that exhibits the behavior in the video or the slowdown you're referencing? If so, that would be helpful for me to track down the issue and get it fixed.

Mario,
now I can see your video. I have already seen that bug from another person. Clipping to a group can also massively slow down PS in this current release or, like in your case, cause artifacts.

Hi Mario, would it be possible to get a copy of the source PSD you're seeing this issue with?

Thanks for reply, my problem is different, the artifact appear on printing too, my macpro don't slow down.
The video now is public, give me a feedback, thanks.

I guess I have similar problem, but I cannot see your video: It ́s not available in Germany. You can read about my problem here:

Does that sound similar? Maybe those bugs are related.
