It's just obvious that it's not intended...
What's the additional benefit to knowing the text "Disconnected" should not be underlined, italic, bold, have no color etc.?
With the introduction of more advanced text formatting and translation this changed to the pretty unreadable format, which I imagine is because it was forgotten to change the disconnect reason from a simple string object to the property of the TextComponent object. Before the change one could easily read the server's output on the commandline. Now it takes up 3 lines and one needs to search for the actual information.
It's just an oversight, and I want to help by making it aware.

This is still an issue in version 1.6.1. Anyone capable, please update the affected versions.

I tried it with the new launcher in version 0.9.5 and snapshot 13w25c and release 1.5.2 and was unable to reproduce it. With the new launcher this bug is fixed for me (Windows 8).

I just tested this with my setup in Minecraft 1.5.1 and the bug is still there. Dear Mods, please update the affected versions for me, as Mojira doesn't give me the permission to.

I experience a similar related issue. My notebook has a screen with a native resolution of 1366x768. If I connect my external monitor with a resolution of 1680x1050 and play Minecraft in a maximized window on it, I can't use all of the inventory of a double chest for instance. Any slot that is higher on the screen than 768px cannot be clicked, neither the white highlighting of the currently hovered cell passes that height.
If I set the external monitor as primary screen in the screen resolution dialog of Windows it works fine, so probably the game assumes just the primary monitor screen realm is important for mouse pointer interaction.
