"Camera" view resolution < screen resolution -> HDR problem

[RedX]

If the "camera" view size/resolution is less than the screen size (whether using multiple monitors or not) and HDR is turned on, the Sun glare is opaque black effect. In addition, any unused screen space contains random pixel noise and the HDR smears it so that a glare effect carries it over to the rendered "camera" area. Apparently with ATI drivers there is an option to cure this (AA edge detect) but in NVIDIA drivers I haven't found anything that helps yet.

 

This problem is unchanged since beta 4 for me.
