Describe the bug:
As stated in the title. See screenshots.

To Reproduce:

1. Enable motion blur in shader settings.
2. Set FPS cap to the minimal value (10 FPS for Sodium).
3. Move the camera horizontally in both directions.

Expected behavior:
Motion blur should work without artifacts of that kind.

Screenshots:

Desktop:

• GPU: NVIDIA GeForce GTX 1650 Mobile
• Shader loader: Iris 1.8.4
• Shader version: 1.3.7

Additional context:
For example, Complementary Reimagined r5.3 does not have this issue.

This is a rather niche issue considering this happens at 10 FPS...

I meant setting fps cap to 10 fps would more clearly indicate an issue. Of course I normally play on 150 fps cap, but I still can notice blinking with naked eyes on very rapid movements.
