Rafiq Reephat, thank you for reporting this and helping make Ubuntu better.

1) Is this something that started to happen after an update? If so, which specifically?

2) To see if this is already resolved in your release, could you please test http://cdimage.ubuntu.com/daily-live/current/ and advise to the results?
