Status: RESOLVED FIXED

(Core :: Graphics, defect)

Description

[aiemaboy]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.16; rv:86.0) Gecko/20100101 Firefox/86.0

Steps to reproduce:

1. visit website: https://gsfresh.com/
2. Check the slide animation on the first page.

Actual results:

It looks very slow and rough, and the first page is not generally comfortable with movement; CPU usage is also seen as relatively slightly higher than other pages and other websites.

Expected results:

I captured the video of the safari as a comparison target. The results I expected are close to this.

Thanks that's great. You appear to be running Software Webrender, which is probably why this is slow. I'm not sure if you deliberately enabled it, but you can try disabling it and see if that fixes the performance on this site: in about:config make sure that gfx.webrender.software is false, and gfx.webrender.all is true.

It looks like this is caused by 3d transforms: specifically ps_split_composite_frag::run
