Hi Alin, I find that I am still able to take a screenshot via the context menu with touch simulation enabled by clicking either the "Save full page" or "Save visible options" while in screenshot mode. However, I am unable to select or drag in the viewport while touch simulation is enabled. Is this what you are referring to? Regardless, it certainly is a touch simulation bug since we are not able to take a screenshot via dragging or selecting a region in the viewport.
Thanks for filing this!
Yes, that is the problem, my fault, I was not clear enough, I've edited step 3...the user can not take a screenshot by dragging or selecting just a section or a region of the page because is not able to drag or select in the viewport.
