firefox button glitch/HW.png

User Agent: Mozilla/5.0 (Windows NT 6.1; rv:38.0) Gecko/20100101 Firefox/38.0
Build ID: 20150525141253

Steps to reproduce:

After a while of large usage of the browser in my computer with HW turned on, Mozilla Firefox would start to go crazy on my computer and would throw browser glitches all over the place. This has NOT happened possibly before version 33 when I had hardware acceleration turned on before in my Firefox and it was working fine.

Actual results:

When I have Hardware Acceleration turned on, Firefox's buttons on the top right, and Back button on the top left would display lines and button glitches and it should not do that at all. The color around the button is slightly lighter on the theme that I have applied on my Firefox. Also another problem would be Mozilla Firefox blacking out and glitching. This would make web browsing on Mozilla Firefox to be impossible to do. There after, forcing me to restart the browser and start over again.

Expected results:

Mozilla Firefox was (and is supposed to be) behaving normally on my computer with hardware acceleration turned on until a certain version of Mozilla Firefox made Firefox behave erratically on my computer.

I do not want to turn off Hardware Acceleration because then it would make web fonts look sharp, small, pixelated and not smooth which I do not like, and that using the YouTube HTML5 player would push my CPU. But, that happens only when I have hardware acceleration turned off in my Firefox.

And also before someone asks this, yes I already do have the latest version of my graphics driver installed on my laptop computer that is experiencing this problem. Yes, I tried to do an update with Device Manager on my graphics driver and it said that it was the latest. Date on this driver is: 04/10/2012 according to Device Manager.

Name of the graphics on my computer is: Mobile Intel(R) 4 Express Chipset Family.
About:Support on Firefox says Unknown on the Adapter RAM, don't know why though.

Could you type about:support and paste the section "graphics", please.

Product: Firefox → Core

Does this also happen with a clean profile [1] and without addons? I'm just wondering from the screenshot if the themes / addons are doing something. Thanks!

Hi Mason Chang,

Yes, this also happens on a clean profile. I have done the "Refresh Firefox" feature before and this problem still occurs without anything on Firefox as well. I can still see the problem happen. (Hardware Acceleration turned on by default of course.)
