Where did the QSGRenderThread go ? (Qt5.4 - Xcode 6 Instruments)



  • After updating to Qt 5.4, I noticed that there is no QSGRenderThread appearing in the Time Profiler. Of course, the thread is still there and running normally, it just doesn't show up on Instruments.

    Before (up to Qt5.3), there used to be a QSGRenderThread where I could track what was taking up cpu time during the sync and render phases of my qml scene. Since my program makes heavy use of OpenGL under QML, I really need to be able to profile that particular thread of my program.

    Does anybody know why it's not there or how to profile the QML thread on Qt 5.4?

    Hi,

    I don't know why, but the Qt engineers do. You can find them at the "Interest mailing list":http://lists.qt-project.org/mailman/listinfo/interest (You need to subscribe first)
