The image full with white lines after exported

[Enny]

Everytime I export the image, I have those white lines all over my images. It looks messy like this most of the time.

I have affinity photo in macbook which is fine, and iPad air which is also fine, but big problem with windows.

It is really annoying, coz I prefer to do editing with my brand new windows laptop than with my getting old and slow macbook.

please help, I hope to get this annoying problem solved ASAP. 

Cheers

Welcome to the forums @Enny

Does the advice in this thread help at all?: https://forum.affinity.serif.com/index.php?/topic/156183-glitch-during-export-photos/

Hi GarryP, yes, it is working now. I downloaded the graphic driver as the advice, I run some test, and it is now working really well. Thanks a lot. I included two photos, I am very relieved that from now on I have no more annoying fine lines all over the images after photo processing in AP.

Cheers
