"Cannot read property ‘0’ of undefined" when image size is undefined

Hi all,

After upgrading my experiments to the latest psychopy version 2020.2.4 my experiments are not working and I keep getting the message “Cannot read property ‘0’ of undefined”

In all my experiment the image size are undefined because I want them to be displayed in their original size:

image605×524 12.7 KB

I think this causes the problem because when I set the image size, for example [1.5,1], the experiment is running, but the size is distorted.

Here is a link to a test version:

Thanks for your help
