We using custom skin for rad controls. The scrollbar looks in IE and Firefox correct but not in google chrome. the result is the same on Telerik demo for rent a car which is a custom skin (clear). See the attachment.
Please accept our apologies for the inconvenience. Since Clear skin was created, a few changes were implemented into the RadFromDecorator skin according the way it decorates scrollbars in Chrome and Safari.
Attached is FormDecorator.Clear.zip, which contains the the fixed Clear skin CSS.
