svg - Firefox 38-40 SMIL problems - very slow speed (resolved in FF version 41 from 22.09.15) -

-

can give information new versions ff, passed after version 37.0.2. knew of bugs in version 38 have been fixed in version 38.0.5. noticed difference in processing speed of attributes 'animate' , 'animatetransform' in new versions of ff, , because of page becomes slow. if remove animate tags:

        <rect x="-1.32" y="-0.63" width="3.64" height="1.26" fill="#ffd9d9" stroke-width="0.0" rx="0.12">             <!--this animation makes half-visible selecting effect -->             <animate attributetype="css" attributename="opacity" to="0.65" dur="0.5s" begin="mouseover" fill="freeze"></animate>             <animate attributetype="css" attributename="opacity" to="1" dur="0.5s" begin="mouseout" fill="freeze"></animate>         </rect>

to this:

        <rect x="-1.32" y="-0.63" width="3.64" height="1.26" fill="#ffd9d9" stroke-width="0.0" rx="0.12">             <!--no animation -->          </rect>

then lose animate(hover) effects , speed became ok, in old version ff(37.0.2) with(with not removed) animate tags.

i created topic: https://bugzilla.mozilla.org/show_bug.cgi?id=1171966

there added examples of code , video them. problem of slowness observed in case of large number of elements on page, if each of them has attribute 'animate'. maybe alse this:

        <rect x="-0.5" y="-0.5" width="1" height="1" fill="white">             <!--it makes half-visible selecting effect -->             <set attributename="stroke-opacity" begin="mouseover" end="mouseout" to="0.5"></set>             <!-- explicitly reverse opacity animation on mouseout -->             <set attributename="stroke-opacity" begin="mouseout" end="mouseover" to="1"></set>         </rect>

in case, use tag make hover effect , change opacity on mouseover. not using css, html5, dom

it nice find similar topics (stackoverflow, bugzilla) or faced problems too. thanks

this has been fixed in firefox version 41 onwards.
