KDE Frameworks Version: 5.54.0
Qt Version: 5.12.0

Comment 2 Nate Graham 2019-01-21 18:20:27 UTC

mthw0, are you using OpenGL animations, or the software renderer?

I don't know. How can I find out?

Comment 4 Nate Graham 2019-01-21 20:32:07 UTC

Open Gwenview > Settings > Configure Gwenview > Image View > Animations

It looks like I do use OpenGL.

Comment 6 Nate Graham 2019-01-21 20:40:38 UTC

And it works with Software Rendering?

Switch from QGLWidget to QOpenGLWidget
