User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:61.0) Gecko/20100101 Firefox/61.0
Build ID: 20180401100341

Steps to reproduce:

Since yesterday's first build, v61.0a1 (2018-03-31) my Firefox window is white when i have Hardware Acceleration enabled.

It was working fine on the build before, then i updated to the yesterday's first build and i got the white issue. I tough the next build or the build released today will fix the issue but nope.  
I uploaded a zip file containing raw data and text data from the Troubleshooting Information Window and 4 pictures.
1'st picture shows the issue, in the second and third picture you can see that the page elements are there but thy are not rendered, forth picture is what happens when i have hardware acceleration disabled - when i open Firefox,  for a fraction of a second i get a white screen, a black screen and then renders the window normally.

It must be something broken with my Firefox profile because it's working fine when starting Firefox in safe mode or creating a new profile.
But the main profile works only if i keep the hardware acceleration disabled. :(

I thought the issue is the gfx.webrender.all, but i turn it to off and the issue is still there..
I fix it by deleting prefs.js and letting it create a new one.
OS: Unspecified → Windows 10
Hardware: Unspecified → x86_64
On the new pref.js enabling gfx.webrender.all made the Firefox Window white again, but this time if i disable that option it will work fine.
Doesn't sound like anything that can be turned into an exploit: removing the security flag.

Is this bug still occurring? If yes: Is everything okay if you set browser.startup.blankWindow to false?
I still get it, even on a clean install and a new profile..
browser.startup.blankWindow;false didn't fix it but it removes the "flickering" that occurs in certain situations.

gfx.webrender.all;true & hardware acceleration enabled = white window

gfx.webrender.all;true & hardware acceleration disabled = flickers for a second on startup, the window appears as white, then black then it renders everything ok.
gfx.webrender.all;false & hardware acceleration disabled = flickers for a second on startup, the window appears as white, then black then it renders everything ok.

gfx.webrender.all;true & hardware acceleration disabled & browser.startup.blankWindowl;false = doesn't flicker, everying is normal
gfx.webrender.all;false & hardware acceleration disabled & browser.startup.blankWindowl;false = doesn't flicker, everying is normal

gfx.webrender.all;false & hardware acceleration enable & browser.startup.blankWindowl;true = normal(I can see the white window for a fraction of a second before seeing the normal window)
gfx.webrender.all;false & hardware acceleration enable & browser.startup.blankWindowl;false = normal
Is there a newer graphics driver for your computer?

No, it's a old IGPU.

Seems that was related to bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1466454
After today's update the browser renders fine using gfx.webrender.all True.
Great, thanks for checking!
