Have you looked at CPU usage in Google Chrome? (Show all processes, it is probably in one of the tab processes not the main appplication.)
This is probably the Chromium engine not anything in CEF or CEFSharp.
Chromium has poor logic for some image decoding. It decodes images to full uncompressed size with 32 bits per pixel. A 13 mega-pixel camera image will use 1 GB of RAM in a Google tab while it is being decoded, even if the display size is 100 x 100.
