Gaussain blur issue

[Jarosław31803479xwxc]

Hi there,

While apllying gaussain blurr  to a grey background I started having strange lines like half curles on the background. Attached is an example.

Didn't have them before.

I am using Windows 10, 64 bit. Newest, regularly updated versions of both Photosop 2024 and Beta Version.

Graphics - Intel UHD 730 with  Intel® Arc™ & Iris® Xe Graphics - Windows*. 

Additionally - Photoshop informs me that my graphics driver is obsolete while Intel Driver and Support Assistant tells me that :"Your Intel® drivers and software are up to date." 

I am not sure what causes the problem  - bad GPU? bad driver? wrong type of file?

Kindly ask for your help

🙂

Hey, @Jarosław31803479xwxc. Welcome to the Photoshop community. I'll move this to discussions for now, and help you figure this out. Please share the system info from Photoshop Help > System info > Copy & paste into a text document > upload & attach here.

I'll move this to discussions for now. Does this happen after a specific series of steps or set of layers? 

These curls are referred to as bands, what is the bit-depth (8, 16, or 32) of your document? 

Here is a recent conversation about a similar behavior reported with Photoshop 25.1.0, experts have shared helpful comments: https://community.adobe.com/t5/photoshop-ecosystem-bugs/banding-when-doing-gaussian-blur-or-iris-blu...
 

Let me know how it goes. Thanks!

Sameer,

Thank you for your reaction. 

The bands appear in both RGB and greyscale mode and at all three bit-depths. The effects is vissible after the first step  - duplicate layer->gaussian blur.

I will certainly follow the link you provided, hope I'll find something there.

Take care.
