Hi Hanabishi,

I reproduced the issue on the latest Nightly 64.0a1 (2018-09-18) (64-bit) on Windows 10.
In some of the samples, the performance is worse than Chrome, close to unusable.
I will add a component in order to involve the development team in reviewing this issue.

Thanks for reporting!

Hi Hanabishi,

I'm having some difficulty reproducing this performance issue on my machine. Could you go to about:support and copy and paste the information to here? That will help us understand the hardware that triggers this issue.

Did this work better in an older version of Firefox and now is slow? If so could you use mozregression [1] to point us at a change that introduced this issue?

Thanks!

Just migrated to Firefox.

I was having a hard time reproducing this issue until I downloaded Firefox 62 (I was using Nightly with and without WebRender), then zoomed out so most of the map is on the screen, then panning around.

That does the trick and we get some really long paints. From taking a profile, most of time spend is inside of FLB. Interestingly enough, I'm unable to reproduce it on Nightly so maybe it has been fixed. Again, with and without WebRender.

Hanabishi, could you try and reproduce this with Firefox Nightly to see if we've fixed the issue in an upcoming release? [1]

Yeah, works good on nightly build! Still less smooth comparing to Chrome but not very noticable.
Great improvement at all, so I think this issue fixed.

This might be a dup of bug 1491631
