IllegalArgumentException when using ScreenRecorder about openrndr

Any idea what your context scaling factor is? I suspect it is fractional (like 1.5 or 2.5)?

The window.scale property (inside a Program instance) is weird: Vector2(x=1.0, y=1.0026315450668335).

This is what the debugger says:

val wcsx = FloatArray(1)  // wcsx[0] = 1.0
val wcsy = FloatArray(1)  // wcsy[0] = 1.0026315450668335

glfwGetWindowContentScale(window, wcsx, wcsy) // ← this line sets values above

I suspect this is caused by something that is out of OPENRNDR's reach. You may want to test against some of the glfw examples in C and see if glfwGetWindowContentScale reports the same scale factors so we can report this as either a glfw or lwjgl bug.

I am leaving the issue open for reference but I cannot resolve it as I don't have the means to reproduce the reported issue.

Is FunctionDrawer from openrndr? I dont' have it.

Hi @clankill3r, FunctionDrawer was removed from the library as there's now an extend overload that takes a function directly.

Closing this as it is getting old

Ran into this problem again. It happens when the system dpi is set to something that is not a multiple of 96. It can be fixed by running xrandr --dpi 96, although I am not sure if this is the right solution.
