Original GitHub issue: https://github.com/rivo/tview/issues/730

Hey folks,
I'm developing an app that uses tview. To manage widgets, I used Grids. There is a minor issue with setting the background color. No matter what I develop, it always selects some random color from the user's terminal.

Terminator:

My terminal's background color is black. I don't know where the gray one came from!

Alacrity:

I tried this one before, and it does nothing:

appGrid.SetBackgroundColor(tcell.ColorBlack)

And sometimes, by opening another page, it goes crazy:

I use SetRoot to switch pages:

NextButton := tview.NewButton("Next").SetSelectedFunc(func() {
		app.SetRoot(stepThree(app), false)
	})

How can I handle this background situation?

Thanks, everybody!

Are you using tcell.ColorDefault somewhere? (If you are, you shouldn't.)

It's difficult to look into this without being able to reproduce this. Can you post some short code I can run which creates this effect?
