Choppy Playback on Shotcut 17.09

Ever since upgrading to Shotcut 17.09, everything plays back through Shotcut choppy. My older version projects, new projects, playlist files, everything. This was not the case on 17.08. Does anybody have a fix, and if not, is it possible to downgrade to 17.08?

Reverting back to 17.08 cures it.
