Issue with glPointSize, which does not appear to affect the displayed point size. The point is always displayed with size 1.
Background: Developing a program which displays some sort of drawing, using OpenGL 4.2. When using the Intel GPU and other GPUs, the points are show up with specified point size. But the same does not appear to work on AMD GPUs and always displays with point size of 1.
GPU: AMD Radeon R7 M360 (Discrete/Hybrid)
What's the possible reason for this issue, and how to get it to work?
