Hi all! I have no idea what's the (hell) is going on. The simplest test... SocketTest::SocketTest() { mSocket=new QTcpSocket(this); QObject::connect(mSocket, SIGNAL(hostFound()), this, SLOT(onHostFound())); QObject::connect(mSocket, SIGNAL(connected()), this, SLOT(onConnected()));

[Development] Exception to source compatibility: adding AA_CompressHighFrequencyEvents flag

Hi, The way you describe the problem sounds like it is specific to tablet events on X-Windows. In my opinion a solution to the problem applied to the 5.6 branch of Qt should also be limited to tablet events on X-Windows. Wouldn't it therefore be easiest to simply not do tablet event
