your limit is 7Mbps (7 million bits per second), and you are already at that limit

Note: That assumes 1 bit per pixel (white/black). Add color, and you are at a multiple of the limit.

Cutout is probably due to dropped pixels. Once you start dropping pixels, the software can't re-sync with the sporadic data stream (like when you get a pixelated picture on your TV). It needs a continuous clean data stream for a few seconds to resync.

I'm guessing that during setup and autonomous, as long as there is no conflict, FMS doesn't throttle bandwidth usage between the robot and Driver Station. Once teleop starts, the data usage increases dramatically, and the 7Mbps limit is then enforced - resulting in dropped pixels, and loss of picture on your DS.
