Hi (I think) I found a Afinity Designer performance bug. I have a photo on a layer and I put an ellipse on it. When I edit it, I have terrible lags that prevent me from working with the document. I got a photo of the lags are also ... Until you can see how the filling does not follow the outline ... I changed the options in Retina rendering, I changed Renderer to WARP - nothing. I opened the document in beta 1.9.1.952 - no performance issues.
