Change that setting back to "Allow sites to save information on this computer" if you want the game to save your sound settings.
I don't know how you get to those settings on chrome.

I have that setting on by default for everything and I don't see the image issues you have.

Tried it but didn't work either unfortunately. What browser do you use? I'm willing to use another for FKG if it fixes the image problems.
