I'm seeing this behavior in Ubuntu 16.04 Google Chrome as well (for a newly created dashboard with 4 generated gadgets in one page). The amount of memory consumed seems to be increasing gradually as the window is kept open. Sometimes the memory usage goes well beyond 1GB.
IMO we should do a profiling to see what causes this much of memory to be used.
