0.4.3 OpenGL Direct HMD window size issue

I noticed in OpenGL Direct HMD mode, the size of the application window affects the resolution in the HMD. If you make the application window size small, the image in the HMD will appear very blocky. As you increase the window size, the HMD image becomes sharper.

I see the same problem with the Oculus World Demo when I compile it to use OpenGL. The problem does not happen when I compile it to use D3D.

Any ideas on how to work around this?

    I'm also seeing this. It looks like OpenGL direct mode can only mirror the window if it's full size.

    Using a borderless window seems to be a viable workaround for this issue. The borderless window can match the resolution of the HMD, even if the HMD resolution is larger than your desktop resolution.

    You can also simply hide the onscreen window, but not until after the Rift has activated.
