User Agent: Mozilla/5.0 (Windows NT 6.1; rv:51.0) Gecko/20100101 Firefox/51.0 Build ID: 20170125094131 Steps to reproduce: Open a few tabs, with graphic intensive websites (google play music, facebook...) on my Thinkpad T450 with Intel Graphic 5500. Actual results: The content zone (everything except the chrome part) of all the tabs becomes entirely black. The only solution is to close firefox and start it again. I see the problem more often now that I have a 22' screen with a high resolution. I'm not sure but I think that the website triggering this bug is google Play music, I can't remember having seen this bug without this website opened. Expected results: no back content

Graphics issue. Type about:support and copy the graphics section. Does it work better with HWA disabled? http://support.mozilla.org/en-US/kb/forum-response-disable-hardware-acceleration

The drivers for Intel(R) HD Graphics 5500 are outdated, could you install the lastest for Win 7 32 bits: https://downloadcenter.intel.com/fr/download/26228/Pilote-Intel-GMA-pour-Windows-10-et-Windows-7-8-1-15-40-?product=86210

problem solved by updating to the latest driver version. thanks

Could you attach a screenshot of the issue when it happens, please.

Black facebook page

on the other tabs, Gmail became entirely white (even after reload), wile Googe maps stayed completely usable (even after reload)

I tested FF 52 on X1 Carbon 3rd gen with the same "HD Graphics 5500" video on Windows 10 Pro, no issues. May be related to Windows 7. Also wondering if BIOS settings are altered w.r.t iGPU memory.

Hum, I've been using FF with hardware acceleration disabled for a few days because of this bug, and today I encoutered it (or a bug with close to the similar effects) again on google news. See attached file.
