GUI "Flicker" After 6.3 Core Update

Just as the title describes. I updated the core on my replication site first to see if it would go pear shaped or not before doing my primary. Now I am seeing a GUI "flicker" or refresh every few seconds. Specifically the Trouble Monitor.

Any reports of this? I'm holding off on my primary for now since the update forced a reboot.

EDIT: I have now updated both cores and all my agents to 6.3 and am still seeing this "flicker" on both my primary core and my replication core. It's pretty annoying.
