I used Photoshop to create my images, these pictures definately match together to create a seamless image. These images that i'm having problems with are already inserted as Tiled Backgrounds. I did resize the images in Construct to make it slightly bigger to fit my layout size as they were a little smaller. But even if i resized the image in Photoshop to the exact size as my layout size and then insert it into Construct, it's still the same issue.
I have just noticed that the gap appears on the black line that shows the layout size, this is with all the images i'm having trouble with.
I've uploaded a couple of pictures to give a clearer view of what i mean.
The 1st picture i uploaded shows how it normally looks when i insert an image. In the 2nd picture, i've moved the image so you can see a gap that appears where the black line is in the 1st picture.
I've tried different things to solve this like increase the layout size, increase the image size but to no avail.
