visual bell whole-screen mode sets the entire screen green
When I enable visual-bell whole-screen-flash mode, a BEL will cause my terminal window to turn a medium green, as if it set the color to start a flash but forgot to unset the color/redraw/something. Subsequent character draws will draw in the terminal window with the correct foreground/background colors.

This debug log captures striking the Delete key at a bash prompt, causing it to emit a BEL and causing this display issue.
