With driver version 10.1, using textureSize() with sampler2DMS argument gives:
error(#155) Internal error wrong operand type built in unary operator function. Type: uniform sampler2DMS
Is this known bug?
Thanks,Brano Kemen
Experiencing the same issue with 10.3.
Thanks for the feedback. It's a known issue and is fixed. The driver will be released one or two months later.
