FPP Update 7115 Never Completes

When attempting to run update 7115 the select query seems to constantly timeout, preventing me from completing the update as written. Locally running it takes about 115 seconds to return 406 records. Attempting to run it in on my development server never completes since it reaches a time limit with the mysql server. For clarity, here's the query that's being run:

SELECT DISTINCT fpp.uuid as uuid, fppr.vuuid as vuuid
      FROM fieldable_panels_panes fpp
      INNER JOIN fieldable_panels_panes_revision fppr
        ON fpp.vid = fppr.vid
      INNER JOIN panels_pane pp
        ON fpp.uuid = SUBSTRING(pp.subtype FROM (POSITION(':' IN pp.subtype) + 1))
      INNER JOIN panelizer_entity pe
        ON pe.did = pp.did
      WHERE (pp.subtype LIKE 'uuid:%')
        AND fpp.reusable != 1
      ORDER BY fpp.uuid;

I'm guessing it's the POSITION or SUBSTRING part that's taking a while. Is there way to optimize the query to improve performance?
