I have an application which fetches pixels outside the border of input texture.The value of this fetch is the last pixel in the row or cloumn depending on whether the fetch is row-wise or column-wise.for eg say the size of texture is 64 X 64 and i fetch 0, 67 the value i get is 0,63.Now this was working fine for NVIDIA driver 100.14.19, 169, 171.05, 173.08.But when I used this with 180.22 the required behaviour I not acheived.
