* 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.

* Support for autostarting scripts (like ones setting ssh-agent and so on) in the user's home directory (~/.config/autostart) is missing.
