Issue with zoom on ultra wide monitor and recording just a part of that screen

[Basti5397]

Hi Ive been struggling with this issue for 2 months now.
Im pretty new to OBS, but I tried my best but I cant solve this issue.

What I do and my setup:
I need to record sections of a website in different formats 16:9, 16:10 and 4:3 on my QHD Ultra wide monitor 3440x1440p. Next to it I have my Laptop screen 1920x1200p open. I have the chrome window on the left side of my ultra wide monitor and i record those 3 formats on that chrome window (I crop it so that the windows bar and chrome tab bar isnt visible).

Now the issue:
on 16:9 the zoom functions well enough, as I dont need to go into too much detail for my videos, but for 16:10 and 4:3 especially I really need to pay attention to not coming to close to the right outer border and the Zoom is off considerably, even worse for 4:3. I know that the mouse position isnt calculated correctly.
The zoom always tends to zoom to much to the left but going close to the right outer border of the obs canva it zooms out of the canva. I tried it for hours to let chat gpt edit the script and set manual source positions but nothing worked.

If theres a fix to this and someone understands the problem pls let me know!

Thanks in advance this would help me a lot :))
