Hi there!
So, there is my problem. On my overlay i'm adding texture(512x512). Then I have to strech overlay to 512x600. After this artifact appears as horizontal black line. I tried to use texture with resolution 512x1024 and it works great, but it is waste of resources...
Thanks in advance
Screen shot?
I guess it was my fault... when useing texture with alpha chanel, "colored" pixels must not touch the texture's edges!
