Summary: Regression : Unnecessarily dim effect is seen while switching to a 'chrome://md-settings' tab opened in the background (was: Regression : Unnecessarily dim effect is seen while switching to a 'chrome://md-settings' duplicate tab.)
Good find. Not only duplicate tabs, any tab opened in the background; e.g., type chrome://md-settings into omnibox, and middle-click on the first suggestion, then switch to the new tab that opens.

Adding RB label as this is a recent regression.

Status: WontFix (was: Assigned)
I was able to reproduce this, then updated (pulled new code)
and was unable to reproduce it. It appears to have been addressed.
