none, that I can think of, sorry.
I'd like to know the contents of the change lists, can you change the
display function around the merge to this:
syncBarrier->enter(2)
std::cout << "display is syncing\n";
std::cerr << "Current Thread CL -- PRE" << std::endl;
Thread->getCurrentChangeList()->dump();
std::cerr << "Client Thread CL -- PRE" << std::endl;
clientHandle->getChangeList()->dump();
Thread::getCurrentChangeList()->merge(*clientHandle->getChangeList());
clientHandle->getChangeList()->applyAndClear();
std::cerr << "Current Thread CL -- POST" << std::endl;
Thread->getCurrentChangeList()->dump();
std::cerr << "Client Thread CL -- POST" << std::endl;
clientHandle->getChangeList()->dump();
syncBarrier->enter(2);
Could you also please set the environment variable OSG_LOG_LEVEL=DEBUG,
run your program
yourApp >yourApp.log 2>&1
and mail me the yourApp.log file (possibly by PM since this is likely a
big file: carsten_neumann AT gmx DOT net) ?
Thanks,
Carsten
