Created attachment 8696356 [details] screencast 1 - Text flickers on codepen.io.webm >>> 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: > https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=e71ed4135461&tochange=7fe3ee0cf8be 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: > https://www.google.com/fonts/specimen/Codystar
Summary: Text flickers (appears/disappears) on http://codepen.io/pen/ when I resize window after hard-refresh → Text blinks (appears/disappears) on Codepen/Youtube when I resize window/change zoom level after hard-refresh
Jonathan, something that you can deal with?
