Seems to break on all screens above 1080p

Tested the Demo on 4 computers:
M1 Macbook Pro: Cuts off capture
2020 Macbook Pro: Cuts off Capture
Dell XPS 4k: Cuts off capture
Gaming Rig 1080p: Works perfectly.

In the below image i captured the entire box but as you can see the capture that gets saved is just a fraction of that.

It appears that when your resolution is higher than 1080p the capture has the wrong resolution so it only records a portion of what you are trying to capture. I have seen the same behavior on other react screen cap libraries so I believe the issue is in the core library that has likely been forked. However i haven't had a chance to deep dive yet.

I can confirm the problem exist - in case if screen resolution bigger than 1080 Capture does not capture selected region correctly...

reproducible on live demo example

after small research the problem related with window.devicePixelRatio
in case if I make screen resolution so window.devicePixelRatio := 1 - capture works correctly
but with maximum screen resolution 3840 x 2160 when window.devicePixelRatio := 1.5 - capture works incorrectly..
