[email protected], this seems different that the issue that is presented in this thread.
Rythal, I realize this might be a bug that is hard to test if it doesn't happen for every quest so I found you a daily quest you can use on an Alliance character. Head to Northrend, Grizzly Hills, Amberpine Lodge. Just off the balcony, you can get a PVP daily quest from Scout Captain Carter. Her quest text extends beyond the frame.
Hope this helps.
