OK. That's not tearing. That's like a bad pitch on an image. (Presumably you only find the second image, IMG_1968.jpg, problematic?) I'm guessing you're using a GL-based compositor, which I fully expect to work poorly. Please try a non-compositing or XRender-based compositing environment.

Thanks. How do I find out what is used as compositor? I am using LXDE. Ilia Mirkin schreef op 2020-06-22 20:18:> OK. That's not tearing.
