Disabling GPU usage for the specific effect solved it. If whoever reading this and has the same problem does not know how to fix it, follow the steps I am going to tell you right now.

Step 1: Add in the effect
Step 2: Scroll to the end until you see the Help section
Step 3: Click the Help Button

Step 4: Uncheck the 'Enable GPU' box in the window that pops up.

Step 5: Click OK and your problem's solved.

The forum won't load the large versions of your screenshots for some reason, so it's hard to see what#s going on, but with Sapphire this typically is either a hardware acceleration problem or a bit depth issue. At the least switch the project bit depth to 16 bpc or 32 bpc. Updating your system's graphics driver may also help. You can also of course simply disable GPU usage in Sapphire and see if it makes a difference.
