Hi botond i was testing a little with 53.0a1 (2017-01-23) (32-bit)... I found that the bug i told you before get worse when the web page has a fixed background image...it seems that FF is trying to calcute or paint the fixed background when its not needed. A few days ago i was comparing scrolling on M.S. Edge and FF and i realize that if the web page has no fixed background image both perform exactly, with an acceptable delay on painting, but if the web page has a fixed background image, firefox shows glitches on that background image that Edge doesn't. Example: http://www.localstrike.net/foros/ ... try to scroll fast and later use firefox's dev tools to remove the fixed attribute from the background image it works good exactly like M.S. Edge. Thanks and sorry for my crappy english _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
