[d2d]Tab switching/Page Scrolling very laggy
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-GB; rv:18.104.22.168) Gecko/20101012 Firefox/3.6.11 Build Identifier: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b8pre) Gecko/20101026 Firefox/4.0b8pre When opening tabs and then the selected page. When viewing the selected page, try changing tabs or scrolling the page. As you can see tab switching and page scrolling with the mousewheel is very laggy. Scrolling using the scrollbar is fine. I've started to see a few ads on various websites cause this lagging behaviour. Reproducible: Always Steps to Reproduce: 1.Make sure no ads are blocked when testing (Clean profile) 2.Open 2 or more tabs 3.Visit the URL test case provided and stay on the page 4.While page is loading try scrolling with the mouse wheel or changing tabs Actual Results: Tab switching and page scrolling is very laggy Expected Results: Tab switching and page scrolling via mouse wheel should not lag This setup the tab switching and page scrolling are fine: Direct2D Enabled false DirectWrite Enabled false GPU Accelerated Windows 0/1 This setup causes the lagging: Direct2D Enabled true DirectWrite Enabled true GPU Accelerated Windows 1/1 Direct3D 10
Confirmed. I see this also on some sites with flash objects on them. Makes the whole UI feeling sluggish, even the higlighting in the menus is lagging behind the mouse cursor.
CC the graphics guys.

If I set gfx.direct2d.disabled = true , the problem does not happen.

Bas, can you route this to the proper component?

Tab switching is fine here, but scrolling on Twitter.com is horribly slow. I have smooth scrolling off.

This bug is about D2D being enabled causing the slowdown with flash ads, and actually about D3D9 or D3D10, interesting.

Presumably this is similar to several of the D2D/flash with wmode transparent performance issues.
If this didn't get a lot better in recent nightlies, please renominate. Async plugin layers should have made this a lot better.

I don't see the issue with Firefox 10. Could someone confirm so we can close as WORKSFORME?
