This is on my Windows 10 surface pro 4. Steps to reproduce 1. create a new image 2. Go to Image > Scale Image to New Size Expected results the image height and width would be the current height and width actual results the image height and width is 0 I looked at the code for this a bit ago. The data is coming into the dialog, but it doesn't seem to be getting set correct. I think these fields are using the new input widgets that can do maths.
This seems to be working fine for me in both the latest master and 3.2 branches. (Qt 5.6, Kubuntu 16.04.2)
It has been a little while since I filed this. I just tried it on master latest and this issue doesn't appear any longer. I am closing the ticket.
