I'm using Ubuntu since 8.04, and have noticed something. It was improving with every single release, but since 12.04 I don't see neither the progress nor at least stability: it is getting worse. The 16.04 tortures me with many glitches on the daily basis, and I found here a bug report already submitted by other people for every problem I have. Most of those reports are YEARS old and still are UNASSIGNED. This tells me: Ubuntu doesn't give a s**t to user experience and bug reports any more.
So I think this particular bug will never be resolved, at list because no one cares. And, btw, Ubuntu became so s**tty that I switched to other distro after many years with Ubuntu.
