Rendering directly on ubuntu server without setting Application.UseSystemConsole = true is broken

I created a fresh ubuntu20.04.3 (server) server VM, installed the dotnet sdk, checked out gui.cs, ran dotnet run --project UICatalog and it looked like this:

In my app, I notice severe drawing issues as well (dead “pixels”, skewed graph axes, …). Am I doing something fundamentally wrong?

What are you using to access the server? are you directly logging in or using ssh? what does $TERM show (i.e. echo $TERM)? Typically you can get odd colours or not showing colors if you are using a different terminal protocol. For example to get putty to work you need to set the app to use xterm-256color (https://github.com/migueldeicaza/gui.cs/discussions/1455)

Setting Application.UseSystemConsole = true makes the CPU usage go to 100%, are there ways around that?

With a Thread.Sleep (10) inside the while (true) of the WaitWinChange () method will improve the performance.

And can I set it easily for the entire catalog to test it?

dotnet run --project UICatalog -usc
