flickering image when raising or lowering the camera

[KansasCS 1]

Every other movement is smooth and without bugs, yet when I raise and lower the camera, the image flickers, as if for a fraction of a second, the camera snaps to a different view and back again, for as long as said command is applied.
Is there a fix? Is this a known issue?

Thanks in advance!

Make sure to remove the controls assignments in your simulator and in FSUIPC if required

Thanks! I though I made sure not to double assign, I missed a few keys. :)
However, sometimes, when switching between presets, I get a flicker aswell. It's not reproducable and frankly I checked if the key is assigned to a different view, but no. I made sure this time.

not sure if u solved it here was my issue with flickering keys..

 

i used the num keys for the camera... this means that the num also effects the camera in fsx through the native assignments. Solution was to turn num lock off and no flickering smoot controls
