Gradient filter | Flickering in Preview and Export

What is your operating system? Windows 10

What is your Shotcut version? 22.12.21

I hope this wasn’t reported before…

Can you repeat the problem? If so, what are the steps?

  • On V1 – Image, video or color clip
    • No filter.
  • On V2 – Transparent clip
    • Gradient filter | Blend mode set to Screen
    • Crop: Rectangle filter

When applying a blend mode in the Gradient filter, preview and exported file shows flickering.
