      Description

        ADDITIONAL SYSTEM INFORMATION :
        known: windows 10, jdk 10, display scaling 150%, 2560x1440

        A DESCRIPTION OF THE PROBLEM :
        it's common practice for higher resolution monitors in windows to have display scaling set to some value higher than 100%, typically 125/150%. however, when using webview with an image that has a filter css property applied (like grayscale or blur) the image is not updated/placed/scaled in the correct position

        STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
        create a webview, apply a css filter property to an image (grayscale for example)

        EXPECTED VERSUS ACTUAL BEHAVIOR :
        EXPECTED -
        the images are rendered with the filtering applied
        ACTUAL -
        the images are rendered with the filtering applied BUT:
        the images are no longer in the same position/scaling

        ---------- BEGIN SOURCE ----------
        any webview will work, just go to:
        http://html5-demos.appspot.com/static/css/filters/index.html
        and the problem will be obvious
        ---------- END SOURCE ----------

        CUSTOMER SUBMITTED WORKAROUND :
        set windows display scaling to 100%

        FREQUENCY : always
