No it's not multi threading. My single threaded non OSG apps do the same, and that's with my OpenGl rendering code called in response to WM_PAINT.
It's something to do with the back buffer swap overwriting the screen without being properly synchronised with GDI but I've never had time to investigate it properly. I think you might have to render to a buffer and then copy it across in response to WM_ERASEBKGND to play nicely with GDI but I've not tried doing that yet. 2008/12/15 Schmidt, Richard <[email protected]>: > Hi, > we are having the same issues here and I think the problem is related to > multithreading. > > One solution may be to sync your drawing thread to the drawing of > windows or to sync the swap operation in double buffered mode. > > I don't know if that helps, it's just a guess. > > Richard -- The truth is out there.
