Brush strokes getting jagged after resizing layer

[Shiwei]

I know this has been an issue that a lot of people had or are having: you take the brush tool, draw stuff and the antialiasing doesn't work.

By chance I noticed a reason why this happens, and it's the weirdest thing.

I have been able to reproduce this bug several times and it goes like this:

1- Open a new file, create a layer and draw something. I'm using the round brush with pressure sensitivity.

2- Now resize that layer and make it bigger. As expected the stroke gets blurred/jagged, nothing wrong with this. (sized-up.jpg)

3- Now, on that resized layer, without changing the brush size or any other setting, make a second stroke (the smaller one in the image). As you can see, now the brush doesn't behave properly anymore and the second stroke looks jagged and blurry. 

4- Finally, create a new layer and, without ever changing any brush setting, make a third stroke (the one to the left). As you can see, the antialiasing works as expected again.
 

Rasterizing a layer seems to "reset" the antialiasing also. I'm not sure if this is intended behavior from the developers but honestly is not intuitive and it creates quite some issues in the workflow.

This seems to add to the long list of small bugs the app has at this point. I'm willing to keep supporting this team and their software, but unless the next version is a major improvement, the app keeps feeling "half done".

Hi @Shiwei,

Thanks for your report!

I can confirm this behaviour is expected, as when transforming a Pixel Layer with the Move Tool to increase the layers size, you decrease the layers effective DPI, meaning any existing or new strokes on this layer will be rendered at this lower DPI value.

When rasterising the layer, Affinity resamples the layer to match the documents DPI, returning it to its original value and therefore returning the brush tool to the expected results.

Equally, creating a new Pixel layer will always create this at the documents DPI, not the reduced DPI of the transformed layer.

 
I hope this clears things up
