RS_ChoicePosition.js

▶ http://disq.us/p/251qwbf

    Window_ChoiceList.prototype.setCenteredChoiceWindow = function() {
        this.width = this.windowWidth(); // Remove this.
        this.height = this.windowHeight();  // Remove this.
        var cw = this.width / 2;
        var ch = this.height / 2;
        var cx = Graphics.boxWidth / 2;
        var cy = Graphics.boxHeight / 2;
        var mx = cx - cw;
        var my = cy - ch;

        this.moveLenear(mx, my);

    };

    Window_ChoiceList.prototype.moveLenear = function (tx, ty) {
        if(this.x >= tx - 0.001 && this.y >= ty - 0.001 && isAudoDisable) {
            $gameSystem.setChoiceMoveable(false);
        }
        var t = performance.now();
        var dt = (t % 10000 / 10000) * 0.5;
        this.x = this.x + dt * (tx - this.x);
        this.y = this.y + dt * (ty - this.y);
    };

it has to refactor the complex variable called 'tx' and remove issue that raises to resize.

/**
 * The width of the window in pixels.
 *
 * @property width
 * @type Number
 */
Object.defineProperty(Window.prototype, 'width', {
    get: function() {
        return this._width;
    },
    set: function(value) {
        this._width = value;
        this._refreshAllParts();
    },
    configurable: true
});

RS_WaveFilter.js

  var alias_Game_Event_refresh = Game_Event.prototype.refresh;
  Game_Event.prototype.refresh = function() {
    alias_Game_Event_refresh.call(this);
    this.updateWaveEffect(); // TODO : Remove this.
  };

it happens sometimes. it seems to read a list of all events when executing certain event command.
