Bug Report

Actual behavior:

Arcade stopped working for me. When running a project (even examples) the only thing that shows is a blank window with the given dimensions without the given background color.

I don't get any warnings or errors in my console, not even in verbose mode. The program does seem to run. Placing breakpoints shows the delta_time changing.

I tried upgrading and downgrading python (3.6.5_1, 3.7.1) and arcade (1.3.4, 2.0.0a1), but without success. I tried running Pyglet (1.3.2, 1.4.0b1) examples, but this gives me the same blank screen.
As far as I know my setup/configuration hasn't change.

I'm running out of ideas and would really appreciate any help. Please let me know if there's anything else I can do to would make things easier.

Steps to reproduce/example code:

Running an example:
python -m arcade.examples.starting_template

My setup/configuration:

python -V
Python 3.7.1`

I have seen something similar once before. Specifically with a student, running Windows on the same exact computer type that I develop on. I haven't seen it happen on a Mac. I'll see if there's a way I can get some additional OpenGL diagnostic info printed out.

Can you run python -m pyglet.info and paste the results here?

Did you do a Mac system update recently? I've heard 3rd/4th hand the people making the SDL library noted that Mac broke something with OpenGL contexts.

My most recent updates:
macOS 10.14; 26-09-18 08:01
macOS 10.14.1; 06-11-18 19:30

If I recall correctly I've used arcade with succes after both updates. Not sure what else might have changed.

Searching for macOS 10.14 (Mojave) and SDL gave me some results that might help:
https://discourse.libsdl.org/t/macos-10-14-mojave-issues/25060
Seems to be fixed in:
https://discourse.libsdl.org/t/sdl-2-0-9-released/25228

I'm not entirely sure how Arcade and Pyglet are connected to SDL.
I thought Pyglet used openGL? openGL seems to be deprecated in macOS Mojave: https://developer.apple.com/library/archive/documentation/GraphicsImaging/Conceptual/OpenGL-MacProgGuide/opengl_intro/opengl_intro.html

If you call set_window_size sometime after creating the window, is it still blank?

@LexVerheesen

Couldn't find a set_window_size function.

Tried the following without succes:

import arcade

SCREEN_WIDTH = 1200
SCREEN_HEIGHT = 600

class MyGame(arcade.Window):

    def __init__(self, width, height):
        super().__init__(width, height)

        arcade.set_background_color(arcade.color.AMAZON)

    def on_draw(self):
        arcade.start_render()

    def update(self, delta_time):
        pass

    # DEBUG: 
    game.set_size(SCREEN_WIDTH, SCREEN_HEIGHT)
    arcade.set_window(game)

    arcade.run()

if __name__ == "__main__":
    main()

Also tried swapping game.set_size and arcade.set_window and both lines without the other.

Yes, same issue here. I'm also on OSX 10.14.1 with python 3.7.1. The window stays blank, e.g. when calling python3 -m arcade.examples.drawing_primitives.

Also, when closing the blank window I get a segmentation fault:

@philippkeller , can you runpython3 -m arcade.examples.asteroid_smasher?

This is with arcade 1.3.4 and 2.0.0a3 both?

I've tried on 1.3.7 and 2.0.0a3, they both show the same issue.

Pygame has the same issue, a temporary workaround is to use python from miniconda. The blank window is solved, but the segfault at the end is still happening.

Any update on the status of this?

I think this will not be fixed very fast. On the pygame thread there's no update, and here they claim it depends on a SDL release which takes another few months

Oh, I need to correct myself!

brew upgrade sdl2

seems to fix the issue of the blank window for the standard python3 binary. But the segfault at the end is still a remaining issue for me

The solution @philippkeller gave also worked for me.

Closed with 2.0 release.

What I have seen is in every instance of example code for Arcade there is never a line that reads: arcade.finish_render()

Without that all i ever see are white screens, once added the screens will then show background color, images and/or sprites.
