Seeing intermittent motion blur in Level sequences

We have complex level sequences containing motion blur.

If we playback the level sequence in a full release build of the game we can capture the video from the Level sequence using OBS and can clearly see frames that are rendered where the motion blur vanishes.

I’ve added a debug hud that renders the ’ global game frame’ to verify that the renderer has rendered a new frame.

When viewing the hud while advancing through the rendered frames, the game frame correctly advances for each frame stepped through,even for the frames where motion blur stops.

This would indicate that the frame has been rendered twice without the Level sequence animation being updated/evaluated. Is this possible and if so do you know if its possible to fix this?

Please note. We are running our game and cutscenes without frame lock.

Thank you in advance for any help given.

Steps to Reproduce
Play a Level sequence that has motion blur enabled.

Capture video using OBS, analyze results frame by frame.

You will see on fast moving objects, motion blur, however now and again no motion of the scene is shown and all motion blur vanishes for said single frame.

Hello,

Thank you for reaching out.

We were unable to reliably reproduce this issue.

Can you please send us a minimal test project that demonstrates this, and include screenshots of the issue?
