      Hi @AnantAgrawal, Just just launch your app from the console. qDebug, qWarning etc. will be printed to the console too (stdout/stderr). Make sure you don't define QT_NO_DEBUG_OUTPUT -- see http://doc.qt.io/qt-5/debug.html for more info.

      Compiled and rebuilt with Qt5.5.0 (beta). Interestingly, the warnings I received when running over VNC or when in high-dpi mode (QT_DEVICE_PIXEL_RATIO=2) no longer appear with Qt5.5.0. So, this is a definite improvement. However, I still receive the 147 (Unknown) error on launch when running over X11 forwarding.

      For future reference, the bug I logged was marked as a duplicate. Here is the link to the original, QTBUG-43454.
