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

and the problem will be obvious
