Hey! So when i use S_RackDefocus and turn up the use gamma, it makes the clips have some weird looking and glitchy scan line stuff. Here's some screenshots.

I've tried this effect on many clips and i still get this glitch. I've also tried reinstalling BorisFX Sapphire, but also didnt seem to fix it.

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.

The bit depth didn't seem to work. Also how do I disable GPU usage? Thank you!

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.

When I click help, it says, "GPU acceleration not available: no CUDA capable card was found." The box is unchecked, though, but the glitches are still there
