>>>   My Info:   Win7_64, Nightly 45, 32bit, ID 20151206030448
STR:
1. Open http://codepen.io/pen/ , wait until the page is fully loaded
2. Click urlbar, press Ctrl+Shift+R to reload the page w/o using cache, wait until it's fully loaded
3. Switch window to normal (not maximized) mode
4. Try to slowly resize the window vertically (to change its height)

Result:       
 All white text in toolbars (on the page) disappears/reappears

Expectations: 
 Text should stay still w/o flickering, just like in GoogleChrome.

This was regressed between 2014-04-17 and 2014-04-18. Pushlog_url:

Looks like it was caused by changes made in bug 964613.
John, I believe you're the right person to ask whether 964613 is the right bug.

The same happens with another url: https://www.youtube.com/ when I resize window in normal mode from the maximum height to minimal height and back. This behavior has the same regression range.

Bizarre. I can reproduce this under Windows 8.1 and OSX.

I recommend to simply change zoom level instead of window resizing in Steps 3,4 - it still shows
the same bug even on those sites where original STR did nothing. E.g. this site:
