Dear Inkscape-devel,
I recently picked up Inkscape again, and there is this screen tearing https://en.wikipedia.org/wiki/Screen_tearing issue I have seen on OS X, and I am wondering what the causes are and how I may be able to contribute.
As far as I understand, screen tearing seems to be an issue specific to GTK2. This happens when I scroll or zoom the canvas, where screen refresh rate is not synced with canvas rendering. This happens either on X-based version (I tried using the official Inkscape app) or Quartz-based version (I tried by compiling the trunk using Quartz variants). I also found that ~suv has this exciting development on native OS X integration with GTK3. The artifacts I have seen are exactly like in this screen recording https://inkscape.org/en/gallery/item/4556/ of Inkscape with GTK2 that ~suv posted.
So, am I correct to say that GTK3 somehow eliminates this problem, even without native OS X integration? How does it do so? If we stay with GTK2 as of now, is there a way to fix the tearing issue?
