Performance of merging layers

[drumnkyle]

I’m following the steps in this article to make changes to a photo: https://www.instructables.com/id/How-to-Make-a-Coloring-Book/

I’m doing it one at a time to about 12 photos. After I apply the black and white adjustment, I select the layers and tap merge selected. This was fast when I was working on just 1 photo but once I had a few artboards with photos, it started taking numerous seconds which seems odd to me. Also, the canvas doesn’t show the right thing sometimes. It starts getting very buggy when I have numerous artboards.

Hi @drumnkyle,

This really depends on the size of your photos/artboards, but I'm inclined to say it's expected. Can you attach a screen recording of your workflow?

Thanks,

Gabe.
