Affinity Photo 2.6 Mask in a group couses artifacts

[PKam]

Specs:

• Windows 11
• Affinity Photo 2.6
• Machine learning modules installed: Saliency and Segmentation
• Hardware acceleration: ON
• NVIDIA GeForce RTX 3070

Description:
The issue can be fixed by turning off hardware acceleration, still creating topic as i had no problem like this in previous versions (only other thing that changed beside affinity version was installing machine learning modules).
When painting on a mask that belongs to a group, strange artifacts appear, as shown in the attached example.
The artifacts get worse the more complicated the layer is and depending on how much I zoom in, often edges of the artifacts get very saturated colors. Sometimes the artifacts will also persist until turning the whole group off and on again.

Steps to Reproduce:
This issue occurs even in new files.

1. Open a file.
2. Develop it.
3. Add an adjustment layer or create a new layer.
4. Group the adjustment or layer.
5. Add a mask to the group.
6. Paint on the mask – artifacts appear.

Everything works fine when the mask is applied to individual adjustments instead of the group

Yeah, having this problem too. Lots of weird pixels appearing where they shouldn't, especially when zooming in and out in a file with lots of groups and masks.

Having very similar issue.  Trying to paint black on the mask and I got a totally different image showing up in the bottom left quarter of the main image, plus a long rectangle show up in the top right quandrant of the image.  I found that by clicking on the brush in the brush selection again, it started working fine.

Hello @PKam,

welcome to this forum.

The same problem here.
I solved it as follows.
Before you apply the mask to the group, set the group from Transfer to normal blend mode, and only then apply the mask. Now the mask should work as expected.
Hardware acceleration is active for me.
I hope this helps. 

Cheers

It is not a mask on the group that is the problem.  After being on a mask in a group, I went to paint on a normal layer mask and that is where the weird stuff started happening.

Welcome to the forums @PKam,

I've confirmed this issue is a regression over 2.5.7 and logged it with the developers, thanks for your report.

Is there a way to roll back to 2.5.7?

[DaleL]

Are you asking if I can roll back or if I should roll back to V2R5?  I do sill have the downloaded version of it in my download folder so yes, I could if I wanted.  Running into some other things that I need to replicate and document also.

Yeah, I would like to roll back, but I was more wondering if there was some way to rollback without taking the exe from a third party.

Thanks for bringing this up, @PKam. I've also had the same issues. Weird, super saturated fringing, glitchy, boxed shaped outlines, ghosting of parts of the image where it shouldn't be...

You can download Affinity Store versions of the installer executable from here:

Click or tap on the ‘Previous versions’ heading to expand the list, and then choose the one you want.

Thank you, for your help! I also hope that this bug is fixed soon, but I can not be too critical because I know that these updates are free.

Not really. You prepaid the updates when buying a licence.

Well, I mean, in my case, I bought the license for the software out at the time and it’s a great plus for me that I get continued updates. So “In My Case” I’m getting updates for free…
