Bug 256003

Created attachment 466106 [details] HTML file demonstrating the issue Elements are rendered incorrectly under some obscure scenarios, the bottom and right edges get clipped. This is most clearly seen on elements with rounded corners because it is most visible where the rounded edge is cut off. As demonstrated by the attached HTML file, I have found that several criteria need to be fulfilled: * The element is inside a container that overflows. * Part of the overflow needs to be caused by a resizable sibling element (like a textarea) which also overflows in itself. * The element is positioned on half pixels (by margin, padding or whatever), in practice, this happened when using a padding of 0.5em with a font-size of 15px. * The element has some type of linear-gradient background-image.
