Sprite errors

[Penhoat]

Hello,

I’ve got a problem with some sprites in my game. These are sprites formed by transparant PNG files which cause some graphical glitches:

This is how it’s supposed to look, and looks most of the time, however when I approach the object, or come close, there’s a line where the “bottom” of the image file is at times:

How do I solve this?

So the white part is normally cut off? Does this line just appear on this sprite or also on others? It seem like an alpha problem -> check your alpha channel a 2nd time
