Coloured, filling bar appearing when zooming in / exporting file (jpeg and png)

[RoryVB]

I seem to have found a bug where when i zoom in certain photoshop designs, a coloured bar appears filling an area. This also appears when i save the image as a JPG/PNG (maby other files aswell). In one of my past designs deleting the background made the issue dissappear. Due to the huge amount of settings i haven't been able to search for the source of this problem yet.

Maby one of you knows where to look for!

Thanks in advance for the help.

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? 

Is the affected object a Shape Layer?

The bar still appears when disabling Graphic Processor settings. The layer is a Rectangle with a few effects

It's a 16 bit RGB color 100CMx70CM 300PPI file btw.

So it is a Shape Layer. 

In a recent thread another user mentioned that setting a Blur of 0.1px in the Properties Panel improved the result. 

Another option might be converting the Shape Layer to a Smart Object.

Applying a blur will sadly automaticly make the bleding options uneditable. Rasterizing it to a layer seems to work best for me currently. Thanks for the help in the right direction.

Made a small mistake. Converting it to a smart object would keep it editable aswell. Thanks!

I cannot reproduce the issue but it seems like it might be a legitimate bug, so maybe you should post a Report over on: 

Photoshop Family

By the way, this is the other thread I mentioned; the problem seems real similar to yours:
