I have always noticed that dragging objects with applied effects (such as something simple like a stroke) lead to poor performance in Affinity Designer, particularly low frame rates and refresh rates. Since upgrading to Yosemite, however, these issues seem to have compounded.
Attached is a video of the performance issues of simply dragging an object with a stroke. Note that the recording accurately represents what I'm seeing on screen; the recording isn't just at a low frame rate.
Is anyone else noticing these performance issues?

Mac Pro mid 2010
