romain.prache@ Thanks for the issue.

Able to reproduce this issue on Mac OS EI Capitan on M-65 build using https://www.browserstack.com/ website, as Mac EI Capitan is not available at TE end.
Unable to reproduce the issue on MacBook Air 10.12.6 and MacBook Pro 10.13.3.

Can observe the browser is running between 5 and 15 FPS in M-65 chrome build.
Could test this issue only on M-65 build as only this is available on www.browserstack.com website.
Attached is the screen cast for reference.

Hence marking this issue as Untriaged for further updates from Dev.

Thanks..

Adding needs-bisect. Also please visit about:gpu, print as a PDF, and attach it.

Adding label TE-Hardware-Dependency as we don't have macOS El Capitan to test the issue from TE-end.

Thanks...!!

Still no reply from #5 -- we need about:gpu to make any progress on this.

Comment 9 by romain.p...@gmail.com, Nov 13 

Hi, any updates ?

Comment 10 by ccameron@chromium.org, Nov 29 

From #5, I wanted a printout from about:gpu on the affected machine.

This is not likely to be fixed -- 10.11 is dangerous to be running at this point.
