Weird difference between expyriment and psychopy engine

GuidoCor

Hi all!

I'm making an experiment in which in a part of it I have to show images and ratings. Weirdly, when I switch from Expyrimient engine to psychopy, they got like pixelated.
I'm attaching a screenshot of both. Do you know why this is happening?
I'm using Opensesame at the last version with Ubuntu 16.04

Hi Guido,

The screenshots are of entirely different shapes, but that's not the issue, right? The issue is that the edges aren't smooth when using PsychoPy?

My guess is that this results from how PsychoPy uses OpenGL to display images, which is different from how Expyriment works (although both use OpenGL). But beyond that I have no clue. Perhaps you could post this on the PsychoPy forum: http://discourse.psychopy.org?

Cheers,
