env.monitor.start('') doesn't display the CarRacing environment in full

[Instassa]

After I call:
env = gym.make('CarRacing-v0')
env.render()
env.monitor.start('results/carrace-1')
and also do some 500 random steps the CarRacing environment gets displayed only partially on my computer (like on the screenshot).

How could I fix this so I can at least see the car?

It's there, you need a bigger monitor. Just kidding, I'll fix it.

[olegklimov]

No there's nothing to fix. Please add env.render("human") to your code. Without this command the window you see is only used as a canvas to draw the scene.

Additionally, to fix large window you can change display DPI on your Mac, or change

WINDOW_W = 1200
WINDOW_H = 1000

in gym/envs/box2d/car_racing.py to smaller values.

Thank you, Oleg, it worked! :)
