The code in Qt that subscribes to slave device events is the explicit tablet-handling code. Checking the code, the touchscreen on my Dell XT2 is being treated as a tablet by the Qt code because it supports a stylus mode on one of its alternate devices.

It sounds like the bug is in the Qt XCB QPA code, which explains why it only started occuring in QML apps after the switch to Qt 5.2.
