I work for a large enterprise and we currently have ESR 17 out on the estate and are about to upgrade to ESR 24 When doing some testing with ESR 24 we have noticed a lot of rippling on FF when using some of our internal web based applications. We have double checked and this also happens on FF 17 Can you please advise what settings can be used to reduce / remove this rippling effect. It is only really there when scrolling up and down on web pages. This does not happen when opening up the web based applications in Internet Explorer. Platform is Citrix (Presentation Server 4.5 / Windows 2003) We have also tried some later more powerful thin clients and this problem looks to reduce / go away. The fact it works in IE showing same colours would say display driver / hardware is all good which leads me to think its firefox config related. Vanilla install, no plugins etc... Please let me know if you require any more info.
