weird motion blur

I'm still having the motion blur problem. The keyframe is set, the movement stops, and the motion blur stops. Next frame: motion blur is back. Next frame and the one after that: motion blur is gone. Then it's back again. This has been going on for months. I'm working around it by cutting the element after the blur and then turning off motion blur, or rendering on an older system, but it's annoying. I've reinstalled everything: After Effects, Nvidia drivers, plugins... but the problem persists.

I really don't know what else to do. And of course, Adobe doesn't have time for these kinds of problems.

I'm working with Windows 11, the latest version of After Effects, an AMD Ryzen 9 9900X 12-core processor, and a GeForce RTX 5070.

Hi oprie_ma,

Welcome to the community! If that motion is kind of a glitch, have you tried purging cache (Edit > Purge > All Memory & Disk Cache) to see if it's helping?

Thanks,

Sumeet
