GLSL matrix arithmetic assignment does not work
My GLSL application runs well with nVidia and Intel GPU. But I encountered a problem with Radeon HD5400 and latest drivers on Windows XP SP3.
It seems to me that the arithmetic assignments multiply into (*=) for mat4 does not work correctly.
-----------------------------------
void main()
{
mat4 R;
mat4 model;
model *= R;
-----------------------------------
Instead, following code works.
-----------------------------------
void main()
{
mat4 R;
mat4 model;
model = model * R;
-----------------------------------
I hope this problem will be corrected shortly.
Regards.
