User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:15.0) Gecko/15.0 Firefox/15.0a1 Build ID: 20120524030520 Steps to reproduce: scrolling on this page : https://chromium-build.appspot.com/p/chromium/console Actual results: causes extremely jerky scrolling with hardware acceleration enabled. With HWA disabled, scrolling is OK Expected results: Scrolling should have been smooth in both cases System : win7 64 bit core i3 370M 4GB RAM ATI 5450M graphic card Happens on both nightly and release version.
created a new profile and still the same issue. But if i restart in safe mode, then the scrolling is OK even with HWA enabled.

Opened the same link in Ubuntu 64 bit. No jerkiness with HWA enabled or disabled. So appears to be a windows issue.
in fact opening this page with HWA enabled causes the whole FF UI to slow down a lot. Any new tab/site/addon tab opened is also quite jerky.
OGL Layer tree rendering seems ok here, I have 60FPS on beagle board for just LayerManager tree paint. It could be that rendering layers it self cause problem, will check on https://ftp.mozilla.org/pub/mozilla.org/firefox/try-builds/mwoodrow@mozilla.com-1aa8c834d846/try-linux/
created a profile with HWA enabled and just opening the page and scrolling in it. http://people.mozilla.com/~bgirard/cleopatra/?report=bd012c4ac82606a75e8c84ca9f705e1946bdd065
gfx.content.azure.enabled = false helps in Nigjtly18.0a1. http://hg.mozilla.org/mozilla-central/rev/c09a0c022b2e Mozilla/5.0 (Windows NT 6.1; WOW64; rv:18.0) Gecko/18.0 Firefox/18.0 ID:20120929030624

This is still reproducible.
aaaaand it still reproduces with/without APZ :)
With APZ and e10s, the page will checkerboard heavily if scrolled fast enough
The page has changed. Cant repro anymore. Will file a new bug if I see the bug again.
