Why does GLFWVidMode#refreshRate() not round the refresh rate? #999

Question

Hey,

I have a Monitor with a refresh rate of 59.951Hz.

When I try to retrieve the refresh rate of this monitor with (LWJGL 3.3.3)

GLFWVidMode videoMode = GLFW.glfwGetVideoMode(monitor);
int refreshRate = videoMode.refreshRate();

refreshRate is 59. Shouldn't it round the 59.951Hz and return 60?

If I set the fps of my application (game) to 59 I get a visible stutter on fast moving elements every second which I don't get with 60 fps...

Thank you very much in advance!

Hey @TCreutzenberg,

This is a known issue.
