Hi,
I was working with Breakout-v0 alright until yesterday, but screen rendering became weird after installing openai/universe.

I tried checking out to previous commits where universe is not used and also tried removing packages that I installed for universe
pip uninstall universe
brew uninstall libjpeg-turbo
brew uninstall golang
It still doesn't solve the issue.
Did anyone experience similar issue before?
edit) I tried making new virtual python environment and it works fine
It seems like dependent package for universe is causing the break

What do you mean exactly with:
"edit) I tried making new virtual python environment and it works fine"
@stefanutti
I use virtualenv and uninstalling universe from current env didn't solve the problem. So I deactivated current env, created new one, and installed packages except universe.
Then gym started to display correctly. So my guess was 'pip uninstall universe' doesn't erase all dependent packages that 'pip install universe' installed, and one of those unerased packages causes the display to break.
This downgrade worked also for me:
It is the version problem of gym.
By using pip install gym==0.10(my case) and modify environment.py :
modify: self.env = gym.make(config.env_name)
to: self.env = gym.make(config.env_name).unwrapped
It is for all games in gym
Thanks for answering this @hikirkendall, please file a new issue against atari_py if this is still happening
