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

Please try out https://github.com/rustdesk/rustdesk/releases/tag/nightly, this version support retina screen, it would be clear.

About the matching layout and black sidebars.
Should this be a new ticket, where the goal is to have a fullscreen that matches exactly the source display?
