Getting frame buffer size for a blit

Hi @songsofsyx,

Welcome to the GLFW forum!

glfwGetFramebufferSize will give you the size of the framebuffer you need.

Have you checked that the issue is the framebuffer size returned by glfwGetFramebufferSize is incorrect, or is it that the glBlitFramebuffer in your program does not succeed?

Cheers,

Doug.
