Issue with Preload Image in RESIZE mode

[AlgoGames]

If I set scale mode to RESIZE and use following code to display a loading mage, it is not always centered. I noticed it happens more frequently on desktop as opposed to mobile. Has anyone else noticed this issue?

        var loadingBar = this.add.sprite(this.world.centerX, this.world.centerY, "loading");
        loadingBar.anchor.setTo(0.5);
        this.load.setPreloadSprite(loadingBar);
