Line appearing above stimulus

What are you trying to achieve?:
I am setting up a Psychopy experiment with visual stimulus images. The images appear with a line at the top, as pictured below.

What did you try to make it work?:
The line first appeared when I was changing the dimensions of the image. I thought it might have been due to the aspects being out of proportion but this does not seem to be it. The line is also not part of the images themselves.

Thanks in advance for any help :slight_smile:

Hi @Paige27, which version of PsychoPy are you using?

Hi @dvbridges

1.84.2 on Windows

For anyone who comes across the issue, I’ve worked it out. The line seems to appear when the stimulus image is displayed out of proportion to the original stimulus image.
