Animation crops right and bottom borders

[jdujava]

I am trying out slight modification of "appear/disappear" animation #1253 (comment):

Animation configuration

animations = ({
    triggers = ["close", "hide"];
    opacity = {
        timing = "0.2s linear";
        start = "window-raw-opacity-before";
        end = "window-raw-opacity";
    };
    blur-opacity = "opacity";
    shadow-opacity = "opacity";
    offset-x = "(1 - scale-x) / 2 * window-width";
    offset-y = "(1 - scale-y) / 2 * window-height";
    scale-x = {
        timing = "0.2s cubic-bezier(0.21, 0.02, 0.76, 0.36)";
        start = 1;
        end = 0.54;
    };
    scale-y = "scale-x";
    shadow-scale-x = "scale-x";
    shadow-scale-y = "scale-y";
    shadow-offset-x = "offset-x";
    shadow-offset-y = "offset-y";
},
{
    triggers = ["open", "show"];
    opacity = {
        timing = "0.2s linear";
        start = "window-raw-opacity-before";
        end = "window-raw-opacity";
    };
    blur-opacity = "opacity";
    shadow-opacity = "opacity";
    offset-x = "(1 - scale-x) / 2 * window-width";
    offset-y = "(1 - scale-y) / 2 * window-height";
    scale-x = {
        timing = "0.2s cubic-bezier(0.24, 0.64, 0.79, 0.98)";
        start = 0.92;
        end = 1;
    };
    scale-y = "scale-x";
    shadow-scale-x = "scale-x";
    shadow-scale-y = "scale-y";
    shadow-offset-x = "offset-x";
    shadow-offset-y = "offset-y";
})

Almost everything seems to work well, but I noticed that while top/bottom borders are visible through all animation, right/bottom borders are cropped out. Best to view the following slowed down video:

animation_slowed.mp4

Is there a way how to avoid this behavior via animation configuration, or perhaps in some other way?

nope, this is a bug.

I think something is wrong in corner radius calculation (although you didn't enable it). the xrender backend does not have this problem until I set a corner radius.
