I just noticed that the flickering nearly disappears when turning off WebGL. Turning on "Pixel Rounding" also seems to help but only on TileMaps containing a few Tiles. But that can't be the solution, right? Did i something wrong or is this an Construct 2 issue?
Not only tilemaps.
In tilebackground also occurs.
The size of the layout and the screen influence the problem.
If the layout is less than 800 x 600 the problem does not occur.
Perhaps this is to be a very large layout with a far far.
The pixels are very small and the screen can not "render".
