Tilemap have 1 pixel on tile borders

have this problem making a test game (downloaded tilemap), and can't find a solution, in the archive the tiles have dimensions of 16x16 and have 2 pixels between each, on tilemap preview it seems good but on viewport and in game the tiles have a little separation (maybe 1 pixel), it looks bad, and I tryed with seamless on and off like you can see on image

first time at c2 forums, thanks in advance

Could you check this for your project setting?

[quote:1bigbxji]Pixel rounding

By default Construct 2 objects can be drawn at sub-pixel positions, e.g. (100.3, 200.8). If the browser is using linear filtering, this can make fine pixel art appear blurry. If Pixel rounding is set to On, Construct 2 objects round their position to a whole number before drawing, e.g. (100, 201). This prevents any blurring, and can also prevent "seams" appearing on grids of objects. Note this does not affect their actual X and Y co-ordinates, which can still be between pixels - it only affects where they are drawn on the screen.

it works on chrome with seamless on, thanks for help me, and nice game

I have the same problem - here are my findings

the seam ONLY shows so far with nVidia cards (also in C2) Intel HD no problem

the seam is only on some browsers like Edge (not Chrome)
