@Shawn: http://anonscm.debian.org/cgit/pkg-kde/qt/qtbase.git/tree/debian/patches?h=ubuntu is currently about Qt 5.5. It has most of the xcb screen related patches backported one way or another (sometimes a bit tricky) from 5.6, but as mentioned here and elsewhere on the net also 5.6 users suffer from related problems.
Qt 5.6.1 is planned to be landed to Ubuntu 16.10, but 16.04 LTS and the bulk of the desktop users will remain on Qt 5.5 so any additional 5.5 patches will be welcome in the future too.
