Attachment: Bug 1524284. Enable WebRender by default on modern Intel desktop gpus.

This enables WebRender on a small subset of modern Intel gpus.

I think you will see a lot of crashes due to Bug 1479795. I used to hit that crash way more easily with WR than without it.
Newer drivers work perfectly, but the one pushed by Windows Update is bugged.

What are "modern intel desktop GPUs"?

I had a not-that-great experience running WR enabled on Intel Skylake (HD 520) on both - Windows and Linux on a 4K display.
Rendering was pixel-perfect, performance however was not that gread - Firefox felt somehow sluggish on many pages.
So no hard numbers, just a "feel" - maybe pushing 4k pixels at each redraw is a bit tough for those GPUs (this makes me wonder how WR will perform efficiency-wise on battery-powered devices - memory bandwidth is quite costly energy-wise).

Right now that means Skylake and newer. Very shortly it will be Haswell and newer.

Is your experience recent? i.e have you tried since picture caching was enabled? If so can file bugs for any pages you encounter this today?

Why is the Intel UHD Graphics 620 (Kabylake GT2) not considered an modern GPU? The UHD Graphics 630 is considered new. I couldn't find any major difference?

The current ids used are the desktop class ones. We should probably expand the list.
