GLFW repeatedly sends GLFW.KeyState'Repeating when button is held down - https://www.glfw.org/docs/3.3/input_guide.html#input_key.

It gets mapped to Up here:

gloss/gloss/Graphics/Gloss/Internals/Interface/Backend/GLFW.hs

Line 348 in af1301a

= do let keystate = keystateglfw == GLFW.KeyState'Pressed

gloss/gloss/Graphics/Gloss/Internals/Interface/Backend/GLFW.hs

Line 352 in af1301a

let keystate' = if keystate then Down else Up

GLFW.KeyState'Repeating should be just ignored and mapping should be GLFW.KeyState'Pressed to Down and GLFW.KeyState'Released to UP
