1658591 - Canvas compositing is slower with firefox 79 and up on linux x64 on NVIDIA proprietary driver

Status: RESOLVED DUPLICATE of bug 1010527

(Core :: Graphics: CanvasWebGL, defect)

Description

[m.sokalski]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:79.0) Gecko/20100101 Firefox/79.0

Steps to reproduce:

Start firefox 79.0 or later, maximize window to at least full-hd screen resolution
Visit Wasm/WebGL http://asciicker.com/y6
Stay idle until fps indicator stabilizes.

Actual results:

Fps value at the top edge of screen shows no more than 45.

Expected results:

Fps value should oscillate in between 59-61.

It can be observed in performance recording that most of the time is consumed by 'Graphics' task (outside of any rendering functions).
I made regression bisection, multiple times, all ends at the same place (attached one below):

looks like this problem affects my intel graphics as well.
Tested on Chromium(~59-60fps) vs FFNightly 81.0a1 (2020-08-09) (64-bit)(~39fps)
Intel Open Source Technology Center -- Mesa DRI Intel(R) HD Graphics 3000 (SNB GT2)
3.0 Mesa 20.0.8
Webrender enabled

Slower performance than Chromium is still expected on Linux unfortunately. You can expect similar performance if you use the Wayland backend or, as soon as bug 1655026 lands, use the EGL/X11 backend. So if you don't observe a regression from compared to FF 78 then this bug doesn't affect you.

FTR, I get steady ~60FPS on my Intel iGPU with FF 79 on Wayland backend (and WR enabled of course).
