Description
Hello. I've stumbled this today.
I'm using Linux Mint 18.3 with Nvidia optimius card. All works great with nvidia accelerator but when I switch to Intel card application is crashing time to time in WebEngine thread.
Under memcheck it shows 'Invalid write' in 'QGLXContext::init' call in QApplication constructor.
Invalid write of size 4 in [...] Address 0x7f17518d7000 is not stack'd, malloc'd or (recently) free'd 1: /usr/lib/x86_64-linux-gnu/dri/i965_dri.so 2: /usr/lib/x86_64-linux-gnu/dri/i965_dri.so 3: /usr/lib/x86_64-linux-gnu/dri/i965_dri.so 4: /usr/lib/x86_64-linux-gnu/dri/i965_dri.so 5: /usr/lib/x86_64-linux-gnu/dri/i965_dri.so 6: /usr/lib/x86_64-linux-gnu/mesa/libGL.so.1.2.0 7: /usr/lib/x86_64-linux-gnu/mesa/libGL.so.1.2.0 8: QGLXContext::init(QXcbScreen*, QPlatformOpenGLContext*) in /home/qt/work/qt/qtbase/src/plugins/platforms/xcb/gl_integrations/xcb_glx/qglxintegration.cpp:336 9: QXcbGlxIntegration::createPlatformOpenGLContext(QOpenGLContext*) const in /home/qt/work/qt/qtbase/src/plugins/platforms/xcb/gl_integrations/xcb_glx/qxcbglxintegration.cpp:187 10: QXcbIntegration::createPlatformOpenGLContext(QOpenGLContext*) const in /home/qt/work/qt/qtbase/src/plugins/platforms/xcb/qxcbintegration.cpp:285 11: QOpenGLContext::create() in /home/qt/work/qt/qtbase/src/gui/kernel/qopenglcontext.cpp:612 12: QtWebEngineCore::initialize() in /home/qt/work/qt/qtwebengine/src/core/api/qtwebenginecoreglobal.cpp:127 13: qt_call_pre_routines in /home/qt/work/qt/qtbase/src/corelib/kernel/qcoreapplication.cpp:332 14: QCoreApplicationPrivate::init() in /home/qt/work/qt/qtbase/src/corelib/kernel/qcoreapplication.cpp:877 15: QGuiApplicationPrivate::init() in /home/qt/work/qt/qtbase/src/gui/kernel/qguiapplication.cpp:1438 16: QApplicationPrivate::init() in /home/qt/work/qt/qtbase/src/widgets/kernel/qapplication.cpp:558 [...]
