Virtual Camera Resolution Lower Than Main Display

[CalvinKroese]

When creating multiple virtual camera displays in RVIZ it starts becoming noticeable that the render resolution is lower than the main 3D display.

I am setting the image width and height to 1920 x 1080, but this does not seem to alter the render window, changing the resolution.

Is this a known issue, and is there a way around it?

I edited the demo.launch to get a 1920x1080 image:

   </group>

(not sure about the roi but made those edits anyhow)

I opened up the output image topic in rqt_image_view, and then save an image to disk:

It looks like I'm getting all the pixels I asked for when zooming into that image:

Does that turn out differently for you?

Thanks for the reply, I also went about checking it in the same fashion which proved to be useful.
