Attached image vsynctest webrender.png

User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.182 Safari/537.36

Steps to reproduce:

I've opened https://vsynctester.com with Webrender enabled and with Basic compositor (Webrender disabled: gfx.webrender.force-disabled option in about:config). I've compared the results.

Actual results:

On Basic compositor I've noticed better result of vsynctester.com. I attach attachments.

Expected results:

I expect the same or better vscyctester.com result on Webrender enabled (GPU acceleration could improve the results). I think this problem is realted to similar problem (low performance with Webrender on Intel HD 5500 at Linux).

Note: in basic compositor (on X11) there is no vsync at all. It's just a fixed ~60Hz timer.

Konrad, can you clarify what you are seeing that is worse?

Lower vsync mark and hills on graph.
