eli0s you are right. The problem are these sprites. But with your example I also get a gap, if the speed is 200 or above.

I made a new example with only one tiledbackground, like eli0s suggested. This seems to work. I tested up to (2000*dt) without a gap.

That's an older problem. Look here h*t*t*ps://w*w*w.scirra.com/forum/scrolling-tiled-background-c2_t63134

I've made an example of an endless scroller with your capx without the wrap behavior.

Hope that will help you.

Is this really a bug? I would rather have an error than a program that doesn't work correct.

I tried the same with the parameter "Set X" and "Set Scale" in the Sprite-Plugin set to the wrong type with a global variable. I get no Error but also no Sprite. Only with "Debug layout i could see that with "Set X" the X postion was NaN and with "Set Scale" the height and width was NaN. And I don't know if I can track down every wrong type of parameter in a plugin with the inspect of Debug layout, otherwise I get an error that I can't track with the Debugger.

Is it possible that a tilemap is faster if I use the tilemapeditor from Construct, instead I Import a tilemap with JSON?

I made the tilemap from the example above with Constructs own tilemapeditor and it seems that is a little faster.

In your Event sheet 1 in the settings of the 'Audio Play'-action you set Volume to the String "Music", but Volume needs a Number. That's why it crashes.
