no display of sequencer output

I know this ( no display of sequencer output ) has been an issue for awhile on certain systems. It used to be that it would at least display images that are 512 x 512, but the latest build won’t even do that. I don’t know if it is a graphics card issue or a windows issue or what, but does anyone know is there any chance it will ever be fixed, or will we just be out of luck until we upgrade our computers? Or is there any way to fix this? I have really been looking forward to using the improved sequencer, so I hope it’s an issue that can be resolved at some point.
