(Note that this is a different issue from the regression in this thread)

I reported this back in November [1] and was told by Kanchan Joshi at
Samsung that it was fixed in new firmware [2]. Lenovo was also contacted
and said they were working on the update in December [3]. I'm not sure
what happened then, but in March, Mark Pearson at Lenovo wrote [4]:

The release process then seems to have started over [5] and the latest
update as of May is that the update is supposed to be released this month.
