In full screen mode, there is always a vertical scrollbar with a minute amount of wiggle room (maybe 1 pixel). This is with a brand new storybook:

It doesn't matter what the actual content is or how you resize the window, although if you make it small enough that the content doesn't fit then you'll get 2 scrollbars:

It seems like the outer scrollbar is completely unnecessary; removing the overflow: auto styling on the offending div from the dev console fixes it.
Would you like to make a PR?
@Hypnosphi done: #2394
I see this same issue in non-fullscreen mode in the top-right panel. Is there a plan to fix it there also?
The offending element is .Pane.horizontal.Pane1 . Removing overflow:auto in the console appears to fix it there also.
@tonyleeper I'm seeing this now too (appears to be a new issue in recent versions)... maybe submit a PR?
Am also seeing this, I would submit a PR but don't know the solution.
Does this issue exist in the alpha version too?
@ndelangen nope, it seems to be fixed in the alpha.
