Updated to 11.0 recently, now Charts are difficult to read

Hi all,

we've made an update from 10.7 to 11.0 in the last week, and now users are complaining about the readability of charts. Charts configured to be displayed as bar graphs now include a white line which seems to show a pseudo-3D-look (as the bars should be shown as nice cylinders or such thing). But if you have many bars in a chart, and on top this chart is displayed in a dashbord, the charts a quite difficult to read, because one third of each bar is simply white, no matter which color you chose for the bar. 

Who the **** came up with this idea without making it configurable? Or is there anywhere an option to have flat bars without blinking shiny reflections? And if you change anything in the old client, why not changing some really important things?

Thanks, Jens
