Set width and height to the element. Set 1px (or any other value, but 1px makes it more noticeable) border to the element with color same as the backdrop color. See reproduction at https://jsfiddle.net/mutf4d52/ Actual results: Border causes some rendering (aliasing) noises appear Expected results: Border shouldn't affect rendering of element in any way
