Since the 2018-06-16 Nightly, Firefox has felt extremely sluggish for me. Every input takes half a second to register, and with Webrender enabled painting feels like it's happening at ~3fps. I tracked this down to a small change from bug 1464039: https://hg.mozilla.org/integration/mozilla-inbound/rev/dfcc5301e872
My monitor is calibrated and profiled using an X-Rite ColorMunki Display and the open source ArgyllCMS toolkit. I'm using a LUT profile which requires gfx.color_management.enablev4 == true, and I'm applying it to every image using gfx.color_management.mode == 1.
If I set gfx.color_management.mode to 2 (the default), the performance issue goes away. So it seems something in my profile is triggering this path, and it makes everything extremely slow. I'm uploading my profile so you can have a look.
I'm on Windows 10 x64 revision 1803 (the April 2018 update), using the 64-bit Nightly, and my graphics card is a GeForce GTX 1080 with the latest drivers. I see the same problem on my laptop with a GeForce GTX 1060 and a different profile (but generated in the same way).
I'm not sure what the policy is on bugs that (should) block security bugs so I've marked this as security sensitive for now.
Steps to reproduce:
Starting from a fresh profile,
1) Set gfx.color_management.display_profile to the location of the profile (or set the profile as your monitor profile system-wide)
2) Set gfx.color_management.enablev4 to true
3) Set gfx.color_management.mode to 1
4) Set gfx.webrender.all to true (optional)
5) Restart the browser
Expected result:
Firefox performs as normal.
Actual result:
Firefox takes a long time to respond to inputs. With Webrender enabled, the framerate on animations is very low.
