Hi,

This is likely caused by the behavior that turns off TAA and motion blur for a frame or two. This is done to avoid glitches when making hard cuts between camera angles.

You can turn off this behavior altogether in the Flow Editor.
On the first B1 Data collection connection, insert a Set Collection Logical module and set its Key to Camera Cut:
Note, this will apply to every camera, even if you did not do the same for B2 and B3 Data collections.

Warmest regards,

Hi,

We will need a bit more information on which type of reflections are you using in Unreal.

For example, if you are using Lumen reflections, you can read some possible solutions here: https://my.aximmetry.com/post/3053-ground-flicker 
Or just having a stronger computer might solve this issue as the Lumen reflections can be recalculated faster.

Warmest regards,
