I'm getting some artifacts/remnants when dragging shapes around, I'm not getting this on 1.5. Figured it might be a Metal or OpenGL problem but switching between them shows the same behaviour, here a gif of what I mean.
Also some texts and icons are blurry and I think this is caused by my dual monitor set up, when I drag affinity designer to the other screen and back onto my mac screen everything is nice and sharp again. My secondary monitor is not retina so perhaps that's the cause, I attached screenshots showing this.
Also the app crashed a few times, not sure the cause but when opening the app again the startup panel is blocking the restore/recovery buttons and cannot be closed. My work around for this is dragging either the panel or the app to my second screen to proceed.
