Affinity Photo Sporadically Cutting Off Pixels When Rasterising

[- S -]

Affinity Photo is sporadically cutting off one pixel from the layer width when rasterising.

This is probably going to be difficult to reproduce, as the issue is sporadic.  In the below examples, with the exact same images and exact same steps, sometimes it cuts off one pixel from the width and sometimes it does not.  When this occurs, the layer is aligned perfectly to the pixel grid, therefore this should not be occurring.

Example 1:

In this video, the image is rasterised using [Document > Flatten].  The first time it works incorrectly and cuts the pixels off (999 pixels wide); the second time it works correctly and doesn't cut the pixels off (1000 pixels wide).

 

Example 2:

In this video, the image is rasterised using [Right-click layer > Rasterise & Trim].  The first time it works incorrectly and cuts the pixels off (999 pixels wide); the second time it works correctly and doesn't cut the pixels off (1000 pixels wide).

 

Example 3:

This video is showing the image aligned perfectly to the pixel grid before rasterising.

Hi @- S -,

This may or may not be relevant but on macOS, I notice that with all image and pixel layers, the image bounding box doesn't perfectly align to the image itself and subsequently there is always a fraction of a pixel of transparent canvas o. You can only see this by zooming in really close but I see this with your sample file as well though I'm not losing a pixel when cropping the canvas or flattening the image itself. I don't know for sure but it may be part of the cause of the issue...

@- S -I haven't been able to replicate so far, but I'll keep testing and will log with the developers if I can get a more reproducible workflow.
