Describe the bug you encountered:

Mac 客户端启动后一闪一闪的，鼠标动一下就闪一下，不动就是白板。

What did you expect to happen instead?

I'm looking for documentation, or even just the source code, for the API for pikvm. I looked through this repo, the website, and subreddit and I couldn't find anything.

If documentation doesn't exist I'm absolutely willing to help with that too..

Please give us some details about the systems you are using:

• Client (OS name and version): Windows 10, VNCtiger v1.8.80
• Remmina version (remmina --version): 1.2.0-rcgit-27
• Desktop environment (GNOME, Unity, KDE, ..): GNOME 3.18.5
• Connecting to (OS and version): Ubuntu 16.04.4
• Connecting via (RDP, VNC, ...): VNCI

I set Remmina listening on VNC 5901
error log:

Welcome to 

I have a 10.3" 1872x1404 display. I'm able to get VNC working on it great, but I can't get VNC to mirror the image, so all the text is backwards.

Go through TODOs in wayvnc and neatvnc that cause abort() or exit and make sure that they have error messages attached to them.
