1027147 - Animations, zooming and panning in the new version of Google Maps are really slow

Status: RESOLVED DUPLICATE of bug 1000640

(Core :: Graphics, defect)

Description

[Marco Castelluccio [:marco]]

Attachment: Profilo 1.zip

STR:
1) Search driving directions between two points (with at least two alternative routes)
2) Click on an alternative route

The animation is smooth in IE, choppy in Firefox.

Setting layers.offmainthreadcomposition.enabled to false makes the animation smoother.

My graphic card is: Intel(R) G45/G43 Express Chipset.

What about leaving OMTC enabled, but setting gfx.direct2d.disable to true?

Up to date drivers?

With direct2d disabled it's better. But disabling OMTC makes a far more meaningful difference.

During the animation (and also panning or zooming), Firefox uses 100% of one core.

Yes.

Anything webgl-related is going to be slow as long as bug 1000640 isn't landed.

Shouldn't bug 1000640 block enabling OMTC by default then? (at least with these poor graphic cards)
Google Maps is nearly unusable.

It's pretty unusable for me too, I really hope we don't intend on shipping omtc on release without that bug landing...

Bug 1000640 has been fixed, and OMTC has been disabled for 32. I'm going to close this assuming that it's no longer an issue, but please reopen if necessary.
