Image sometimes flickers #810

Preliminary Checks

Description

Hi, while i am testing the zedm camera, I found this issue: the images sometimes flicker.

I put the camera upwards. The camera stayed static during the recording. As you can see in 3 images, frame 240 is the same as frame 242, while frame 241 looks really strange.
