Broken: version: 3.2.0 Alpha, branch: master, commit date: 2022-04-07 23:10, hash:
87a3bf3356Short description of error
This is happening to me long time already but I never could pinpoint it, like around 1% of frames are appearing to be glitched. I can't share the project but I will try to replicate it with another file and show you the details.
Exact steps for others to reproduce the error
Turn on motion blur and render some animation
Also this bug is not always consistent

Changed status from 'Needs Triage' to: 'Needs User Info'
Does this also have Persistent Data enabled? (then it might be the same as #96822 (Persistent Data Causes Render Errors for Motion Blur)
Otherwise: please share your (minimal) example .blend file where this fails
Yes I have persistent data enabled
You also mention Optix, could you check without it?
And with Persisten Data disabled?
Again, this sounds like #96822
Yeah I think it's the same bug, with persisent data disabled it doesn't exist makes glitches. Thanks for the help at least I can render now <3
OK, thx getting back, will merge reports then
