Color rendering mismatch on all odd vertical pixel count-sized resolutions

[skull-squadron]

Bug Description

Every vertical resolution with an odd number of pixels (default for half resolution on 16" MBP m1) renders color-containing image data offset up.

Grayscale items will be in their original position relative to the framebuffer, however color-containing regions appear offset.

How to Reproduce

Remote

1. Set mac built-in display to resolution 1728x1117
2. Start background service

Local

3. Connect to remote from a Windows client

Expected Behavior

Colors rendered on the remote display should line up similarly to even vertical pixel-sized displays.

Operating system(s) on local side and remote side

Windows 11 22H2 -> macOS Sonoma 14.2.1

RustDesk Version(s) on local side and remote side

1.2.3 -> 1.2.3
