Comment on attachment 304037 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=304037&action=review I noticed this a while ago but didn't fix it yet. Thanks for tracking this down. > Source/WebCore/ChangeLog:9 > + There seems to be a bug in DrawThemeBackground when the device context is scaled. > + We can work around this by scaling the drawing rectangle instead. I'm not sure this is a bug in DrawThemeBackground. I think we just need to scale the drawing rectangle or use something like https://msdn.microsoft.com/en-us/library/windows/desktop/dn384112.aspx in order to get correct behavior.
