P: Export As now crops to contents instead of using the mask

Hello there,
There are some problems with exporting layers as png.
Before PNGs were saved with the mask area, but now they are exported cropped.
Working on Macbook m1, I don't have this problem on my another laptop- Macboo pro i9 late 2019
Have you faced such a problem?

Hopefully the following script will suffice as a short term work-around. An action can also do similar. I also agree that this is a step backwards, not forwards and that having to come up with work-arounds is far from ideal.

Adds a 1% white pixel to the upper left and lower right corners of the open document
Note: Assumes that the active layer is a raster layer can be filled!

If there is any transparent pixel it will be turned into white pixel.

The new Export As will ignore all fully transparent pixels. Using a mask to add "white space" around an object wouldn't work in this context. The best way to approach what you are trying to accomplish is to use the Cavas Size settings within the Export As dialog. In your screen shot, the current settings are 165x165, the size of the circle. You can simply set this to 512x512 and you would get the desired effect.
