The number of depth frames differs too much from the number of color frames

  In the frame numbers that you mention, the number of color frames is exactly half the number of depth frames.  I wonder if that means that the depth is running at 60 FPS but the color stream is lagging at half that.

  I hope that the lengthy discussion in the link below (which features a user who was getting 30 FPS from depth and 15 FPS from color) will provide some further useful information in regard to getting closer to a solution.

  When I turn on all the lights in the room, the depth and color are basically in sync, but this happens when I turn on only two lights, so I think the problem is caused by light.

  During my research I came across a case where the color and depth timestamps were going out of sync, but not the number of frames so I was not sure that it was relevant in this case.  Dorodnic the RealSense SDK Manager thought it might be related to auto-exposure.  I will point you to it so you can decide for yourself.

  As mentioned in this discussion, you can force a constant FPS by disabling exposure_priority.
