Visual bugs in editor but also in export

[jonkl]

Dear support, 

I have from time to time problems with Affinity Designer 2.4.2 on a MacBook Pro M3 Max (MacOS Sonoma 14.3.1). While doing some pictures collage, sometime a few visual breaks occur in shapes or masks. When this happens, I save my project, close the software and then it works again. But I don't know what causes that kind of behaviour. I tried to export the file in JPEG and PNG and the artefacts were present. However, when exporting to PDF, the output file was clean (as expected). 

Thank you in advance for your support and assistance. Best regards

As an addition, I have to say sometime the visual artefacs disappear when I adjust the zoom level in the editor but not always. And in that case, the layer structure is really simple. Rectangle with border and drop shadow as mask for the pictures. Nothing more.

Hi Jonkl,

 If possible could you provide a copy of the Affinity file in question so I can look into this further with you? I will provide a link to our DropBox below so you don't have to post the file publicly. If you would rather not provide the whole file you could always copy one of the problem objects over to a new document and then send me a copy of that instead.

Thanks

Dear Callum, 

I was able to remove the personal pictures from the template and the problem is still present in the file. So please investigate as possible. If I export to jpeg, sometime the problem is present, different resolutions produce different artefacts. However the PDF export is clean and I was then able to convert it to JPEG using Affinity Photo 2... The way is a bit long...

Thank you in advance. Best regards, Jonathan

Try set off HW Acceleration in application Preferences.

The rendering of outside-aligned strokes appears to be the problem.

Workaround: double the width of the stroke, make it centre-aligned and change order to 'Draw stroke behind'.
