This might be a regression caused by switching to requestAnimationFrame for updateLayoutSoon.

Heh, I was just going to file this bug, but my video clip got buried somewhere.

(In reply to comment #2) > This might be a regression caused by switching to requestAnimationFrame for > updateLayoutSoon. Good call! I caused this regression in http://trac.webkit.org/changeset/188494. The flashing as the navigation bar updates is also visible when selecting nodes in the DOM tree content view. Working on a fix.

The problem still persists on r194173. (Should I reopen bugs for cases like this?)

Created attachment 278447 [details] WIP This fixed the issue when the the DOM path bar isn't very long, e.g. the nesting isn't very deep. I'm not sure what difference does it make. I'm continuing looking.

It should move to the Private section or, since it is only used once, inlined next to the caller above.

With the last patch the icons on the right are still blinking. I need to combine my two latest patches into one.
