https://bugs.freedesktop.org/show_bug.cgi?id=30122 Summary: r600 scrambled render when using 2d texture sample for 1d texture co-ord in fragment shader Product: Mesa Version: git Platform: Other OS/Version: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@xxxxxxxxxxxxxxxxxxxxx ReportedBy: thomas.jones@xxxxxxxxxxx Created an attachment (id=38612) --> (https://bugs.freedesktop.org/attachment.cgi?id=38612) small program that triggers the bug Using a shader like this results in a strange scrambled rendering: uniform sampler2D src; uniform sampler1D pal; void main() { gl_FragColor = texture1D(pal, texture2D(src, gl_TexCoord[0].xy).x); } it looks like in addition to just being messed up it also gets the texture co-ordinates wrong (I'm rending with GL_QUADS, the two triangles that make up the quad seem to be interpolating differently across the middle) -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
