Thanks Lee for your answer and for your interest in my issue. All the images I'm working on will be used on my commercial website that is not online yet. So screen recording my Affinity Photo document with all the images and names (the layers names) raises at the moment confidentiality concerns. I hope you will understand. I've just found a kind of workaround to my problem. I lock all the layers and groups in the document (50+) from the parent groups. I unlock the layer on which I want to work then lock it again. This way, images apparently stop moving. But this is tedious and not very practical.... I must add that only PNG images, not JPG, are affected by these changes in position and size.

I tried to lock all the groups and layers in the document, from the parent group to all child groups. I saved. I reopened: images moved again on their own!

Hi Alfred, thanks for your answer. Indeed, each layer containing an image is inside a succession of groups and sub-groups for better organization and readability. I can't lock the parent groups to prevent any movement and changes in size otherwise I couldn't work on this document at all! The erratic changes in position and size happen when I work in another sub-group of the same parent group. Does it mean Affinity Photo cannot manage a tree structure of groups and layers?

Hi all, I have a serious issue with Affinity Photo v1 for mac that is getting worse and worse. I use a document which is a template (1000x1000 pixels) for all the product images I sell on my website, mostly clothes. I have about 50 images sorted in different folders that I arrange and display individually. The problem is the images randomly move on their own after I arranged them. I tried to lock the layers but they move anyway. I quit the app, restart but same problem. Sometimes images are just moved inside the document, sometimes they are also reduced in size. Movements happen when I close the document or during my open session when I'm working on the images. This is hours and hours of work lost (images imported, corrected, adjusted...). I couldn't find any similar issue on this forum. Thanks in advance for your support.
