So, might be a bit fiddly to try and prevent frame update in all situations that SwapBuffers retuns false.
I wondered if we could address this issue by only reporting the error if GetLastError is also non zero. Works for me!
The value returned by GetLastError is zero when SwapBuffers is called for a minimized or off screen window, so we could just add a check for this.
Just say the word, and I'll post my modified GraphicsWindowWin32.cpp to the submissions list. ;-)
Cheers.
Chris.
e.g.
//------------- OSG- 2..8 ----------
void GraphicsWindowWin32::swapBuffersImplementation()
{
if (!_realized) return;
if (!::SwapBuffers(_hdc))
{
reportErrorForScreen("GraphicsWindowWin32::swapBuffersImplementation() - Unable to swap display buffers", _traits->screenNum, ::GetLastError());
}
}
//------------- Modification to remove redundant warnings ----------
void GraphicsWindowWin32::swapBuffersImplementation()
{
if (!_realized) return;
if (!::SwapBuffers(_hdc) && ::GetLastError() != 0)
{
reportErrorForScreen("GraphicsWindowWin32::swapBuffersImplementation() - Unable to swap display buffers", _traits->screenNum, ::GetLastError());
}
}

"the latest SVN revision cannot be build under Windows if ?OSG_USE_UTF8_FILENAME? config option is enabled. The error occurs in ?FileUtils.cpp? file, line 663, since there is no UNICODE-capable version of the ?GetProcAddress? function. The ?OSGDB_WINDOWS_FUNCT_STRING? makro is defined as follows in that case
#define OSGDB_WINDOWS_FUNCT_STRING(x) L ## #x L"W"
Thus the second parameter cannot be converted from wchar_t to LPCSTR. Should we convert the second parameter from wchar_t* to LPCSTR or use the same definition for the ?OSGDB_WINDOWS_FUNCT_STRING? makro in both cases?
The second error occurs in the same file, line 669. The second parameter for the ?pGetModuleHandleEx? function should be defined as wchar_t, but it?s defined as ?static char static_variable? in the line 667."
Converted Present3D across from using libxml2 to using the new osgDB::XmlNode/XmlNode::Input classes from Xml Parsing.
This changes removes the dependency on libxml2, and allows the present3D application and p3d to work on all platforms.
This fix reverses the vertex order and sets up proper OpenGL facing. I didn't notice this problem until I started using the plug-in in my own code (osgviewer seems to not enable backface culling)."
