Unable to cover full bounding box on super ultra wide

[Hezkore]

My monitor is 5120 x 1440, so the image is very wide.
I have my bounding box for the desktop capture set to 1920 x 1080 and "Scale to inner bounds".
But when I zoom in it doesn't actually cover the entire bounding box, it only covers what it already renders.

Is there a way to fix this?
I've attached a video demonstrating this, notice the black bars at the top and bottom.

I'm not exactly sure how the "Set manual source position" option works, but I've modified the code so that it at least makes sense to me.

By changing these lines:

obs-zoom-to-mouse/obs-zoom-to-mouse.lua

Lines 786 to 789 in 53dc1a5

	local new_size = {
	width = zoom.source_size.width / zoom.zoom_to,
	height = zoom.source_size.height / zoom.zoom_to
	}

To:

local new_size = {
    width = monitor_override_w / zoom.zoom_to,
    height = monitor_override_h / zoom.zoom_to
}

I get the expected result when setting "Monitor Width" to 5120 and "Monitor Height" to 1440, then "Width" to 1920 and "Height" to 1080 in the "Set manual source position" menu.

I've attached a video demonstrating this.

@Hezkore That's a great workaround. I suspect the change may break some scenarios depending on the sort of zoom source and/or crop values it might have, but I'm glad you got it working for your case.

To be honest, there are so many different sizes and positions in the script now that even I get confused about what they all do. I probably need to overhaul them at some point.

Thanks for posting this, I'm going to point some others at it to see if the same workaround fixes their issue.

Worked for me too! Thank you for sharing :)

I might cry. Finally a zoom script that works. Thank you so much for posting this workaround for ultrawide.

I think I have a similar issue. My monitor size is 3840x2160, but I have it scaled down to 1920x1080 for readability in my settings. My zoom doesn't quite zoom in on the cursor, nor does it follow it. Here is a gif

Update: I was able to resolve my issue.

1. Checked my Video setting. Made the base (Canvas) Resolution the same as my monitor resolution.

2. Set manual source potion to the below
