Bugs

Graphics corruption may occur on Intel drivers, upstream bug: https://bugs.freedesktop.org/show_bug.cgi?id=79448
Dragging icons out of Folder instances can occassionally partly misrender the icons attached to the mouse cursor on nVidia's proprietary drivers. Qt 5.4 is introducing new API that will make this much more robust.
XEmbed-based systemtray not supported anymore, for workarounds see http://blog.martin-graesslin.com/blog/2014/06/where-are-my-systray-icons/ http://notmart.org/blog/2014/06/systemtray-plasma-next-and-gtk/
Override redirect windows (e.g. tooltips, Window Switcher, etc.) are completely translucent on first show, upstream bug: https://bugreports.qt-project.org/browse/QTBUG-39329
The Meta (or "Windows") key is not recognized as modifier key. Patch merged into Qt for 5.3: https://codereview.qt-project.org/#/c/87615/
Aurorae window decoration themes might crash the window manager, upstream bug: https://bugreports.qt-project.org/browse/QTBUG-39336
Text in QML (Plasma Applets and/or Aurorae windows decorator) can get corrupted/turned into boxes: https://bugs.kde.org/show_bug.cgi?id=336615
Battery monitor tray icon does not reflect AC adapter state - that is gone from Solid Devices, Power API not yet ready
Running a Qt5 application using libvlc crashes that application, apparently because of outdated/non-existing VLC cache. See launchpad bug https://bugs.launchpad.net/ubuntu/+source/vlc/+bug/1328466

No holidays or calendar events displayed in the Plasma calendar - Awaiting KDE PIM libraries to port to KF5/Plasma5.
Unable to edit individual locale settings - Can change locale used for setting groups such as currency or date/time, but cannot yet modify individual settings like short date format - Awaiting support upstream in Qt.
Support for autostarting scripts (like ones setting ssh-agent and so on) in the user's home directory (~/.config/autostart) is missing. Support for applications using .desktop files is still working, however. A possible workaround involves creating .desktop files which launch the interested programs. Discussion is ongoing on how to handle this missing feature.
