Set position to(Mouse.X,Mouse.Y)Chrome performance

Hi here's a capx with a simple event:

everytick-apple-set position to (Mouse.X, Mouse.Y)

In Firefox and IE it runs smoothly but in Chrome there is a little lag in the update of the position of the apple.I'm making a game and the controls are based on this.Can someone please check if this happens in your setup.Thanks.

Thanks,i'm using R74(wainting for a a more stable version) but if this happens with the capx file aswell, it has to be a chrome problem.Any suggestions?

@Cecisco: the very latest version (r79.4) is the latest stable version.
You really should update to it.

Some browsers use techniques like double-buffering that make the game run faster - but this imposes a one-frame delay, so things like this are always one frame behind. It's typical of practically any game engine as well.

You should not try and use sprites to replace the mouse cursor because of this problem. It can make input really laggy and frustrating. If you're just dragging around other objects, the delay shouldn't be a problem.

My game uses a sprite for a mouse cursor. What I do is I don't check for Mouse.X or Mouse.Y, but rather the mouse cursor sprite's X and Y. That way you don't get the appearance of that delay in positioning. It's still there obviously, but it doesn't matter. Works great for my game (which is a point and click adventure by the way).
