Issue with radeon when I add values to uv

Question asked by promero on Oct 1, 2016



I have a issue only in radeon cards. I test my shader with other graphical card and works fine.

This issue is tested with last iMac ATI radeon R9 M395 2048 MB.


When I add some values to uv in fragment shader, the border or the triangles are not correct. ( With mipmapping )

Without mipmapping works fine.


I write a simple code. Attach you will find a picture to see the problem.


vec2 resultado0=TexCoord0 + vec2(0.5,0.5);

vec4 tTex =texture2D(tTextura, resultado0);

gl_FragColor =tTex;


Thanks in advance
