Sharing between mac in fullscreen does not display the same resolution

[yene]

Bug Description

I run two macbook pros with identicial resolution side by side (1800:1169).
When I share the screen in fullscreen, it is not identical.
In the scaled mode it is small, in the adaptive mode it is blurry, and there are sidebars sometimes.

I expected that both macbook pros next to each other display the same resolution and sharpness.

How to Reproduce

1. Share screen between two macs that have the same resolution.
2. Compare what is displayed

Expected Behavior

Both macs display the same thing

Operating system(s) on local side and remote side
