Steps to reproduce:

Is it time?

I've been using OMTP for ages with no issues on BQ Aquaris X5 and Sony Xperia X Compact.

On my low end BQ phone I think it helps keep scrolling smooth when I'm scrolling while the page is still loading. On the Sony I'm not sure I can tell any difference.

Hi Mark,

Could you help me with some more precise Steps to reproduce, because I am not very clear on the issue reported by you.

Thank you!

Oh, sorry

OMTP is Off Main Thread Painting

It's enabled on Desktop but is disabled by default on Firefox Android. I have had it enabled for many months on my Android phones and I think it does improve performance on slow phones. So perhaps it's time to enable it by default on Android??

I think this bug is one for the Graphics team.
