Issue

I'm trying to lower the opacity of the background color, using backgroundColor: 'rgba(0,0,0, 0.5)' but it's not working, the background has 100% opacity no matter what.

If I change to another color (not caring about the opacity) it works, but it ignores the opacity.

opacity is not supported by electron on linux/windows. just in mac

We should probably put a notification when a user tries to get transparency in windows/ubuntu and link to the comment by electron.

Adding a comment in config file should be ok

Yeah, I didn't know this. With a comment in the config file it would have been enough.

Thanks.
