Created attachment 162219 [details] Example file
Created attachment 162234 [details] Example file Same when dragging the fontwork around
I do not see anything wrong with either of those files.
Created attachment 162325 [details] Screencast Screencast 1 This is not specific to Skia (GDI does the same thing). Didn't look at it while reporting.. also in older versions :-(. So feel free to ignore 2. Yes, the dragging image around this way is stupid, but change it to the idea of dragging an image into position.. (with mouse or finger on a touch screen)

With my recent commits, this should now be better (or, as far as Skia is concerned, probably as good as it gets).
