My application has an OSG view and a second non-OSG OpenGL view.
Occasionally, I'm getting a crash in
GraphicsWindowWin32::swapBuffersImplementation() with what looks like a
bad _hdc. The crash is an access violation due to an attempted write to 0.
I think the relevant code is:
void GraphicsWindowWin32::swapBuffersImplementation()
{
if (!_realized) return;
if (!::SwapBuffers(_hdc) && ::GetLastError() != 0)
{
reportErrorForScreen("GraphicsWindowWin32::swapBuffersImplementation() -
Unable to swap display buffers", _traits->screenNum, ::GetLastError());
}
}
I'm not certain if this is correct because the crash is actually
happening down in the atioglxx.dll file. Does anybody know if AMD has a
public symbol server?
I think it has something to do with OpenGL state between my two views
because the crash normally happens when I'm manipulating my non-OSG view
(and my OSG view is still drawing nonstop in its own thread). Is this a
bad thing to do?
