Hi,

turned my OL-Client from OL 2.12 to 2.13.1
Everything works fine but I have performance problems with my UI Elements
(KendoUI / JQuery e.g. drag n drop of modal windows) over the map.

Here 
https://github.com/openlayers/openlayers/blob/master/notes/2.13.md 
I've read this part:
"To make the zoom animation smooth, GPU support is active by default for
rendering tiles. 
This may interfere with UI widgets that overlay the map. 
In this case, it may be necessary to turn GPU support off, which is done
with the following css declaration:"

img.olTileImage {
    -webkit-transform: inherit;
    -moz-transform: inherit;
    -o-transform: inherit;
    -ms-transform: inherit;
    transform: inherit;
    -webkit-backface-visibility: inherit;
    -moz-backface-visibility: inherit;
    -ms-backface-visibility: inherit;
    backface-visibility: inherit;
    -webkit-perspective: inherit;
    -moz-perspective: inherit;
    -ms-perspective: inherit;
    perspective: inherit;
}

I've added the css, but nothing changed.
Any idea?

Thanks
Sven
