Attachment: Glitch.png

User Agent: Mozilla/5.0 (Windows NT 6.3; Win64; x64; rv:42.0) Gecko/20100101 Firefox/42.0
Build ID: 20150701030207

Steps to reproduce:

1. Start firefox v40beta or later version of aurora/nightly
2. enter text in url bar
3. glitch appear

This affects even fresh created profile but doesn't affect "safe mode".
This doesn't affect v39.
This affects win32 and win64.

I have found that if this css exists in chrome/userChrome.css, the glitch is gone.

/* Bug in v40 : this must be any color but "none" */
#urlbar-container:not([focused="true"]) .textbox-input-box.urlbar-input-box {
	background: white;
}



Actual results:

text in url bar doesn't appear. (see attachment)


Expected results:

text in url bar should be there. (see attachment)

This sounds like it's related to graphics acceleration, if safe-mode fixes the problem.

In Preferences > Advanced > Browsing could you uncheck the box "Use hardware acceleration when available" and restart, and see whether this also solves the glitch?

Turning off "Use hardware acceleration when available" also solves the glitch.

The display adapter is "Intel GMA 4500".

[Tracking Requested - why for this release]: graphics glitches seriously affect user quality perceptions. Hardware-specific issues will only be noticed by a small % of the population.
