Description
Heads up - I'm using GLFW on OSX Ventura (M1, hiDPI) and the framebuffer is mismatched in the capture since I removed my normal-DPI monitor:
It's of a single window (capture tool).
Should look like (screenshot)
.
I'm supposingglfwWindowHint(GLFW_COCOA_RETINA_FRAMEBUFFER, GLFW_TRUE) would solve it ... it's undefined for me as of this time. Looking into it.

Research direction
Start by reproducing the mismatch in the capture tool on an M1 Mac running OSX Ventura with only the HiDPI laptop display connected. Inspect how GLFW framebuffer settings are used, including GLFW_COCOA_RETINA_FRAMEBUFFER, and compare the result with the expected screenshot; done means the single-window capture matches the expected dimensions and appearance.
