We have had similar complaints with a qt3.3.8 integrated viewer.In our case a composite viewer with four views with splitters in between.
I found one 'workaround' which is: > go to the advanced display settings, advanced, troubleshoot and ... disable hardware acceleration ... ...... pff... but the Intel graphics drivers sometimes don't provide this menu. If I check the log (with set OSG_NOTIFY_LEVEL=DEBUG) i see: GraphicsContext::registerGraphicsContext 07391228 close(1)07391228 close(0)07391228 GraphicsContext::unregisterGraphicsContext 07391228 Viewer::startThreading() - starting threading Viewer::startThreading() - contexts.size()=0 while I should see: GraphicsContext::registerGraphicsContext 0x95187f8 Relaxing traits GraphicsContext::createNewContextID() creating contextID=0 Updating the MaxNumberOfGraphicsContexts to 1 Viewer::startThreading() - starting threading Viewer::startThreading() - contexts.size()=1 Any suggestions are very welcome.
