This resizing code looks confusing... can you explain why it is necessary to detect change in size and immediately order the output to resize itself again?

[BDisp]

When windows is resized the buffer isn't correctly resized. So the code force resize the buffer correctly and thus there is no scroll buffer.

To avoid this.

But I recognize that isn't good as is. So, feel free to change all you want.

I spend much time to deal with resize window issues using VSDebugConsole and WSLg but finally I realized that doesn't worth because seems that them are buggy working as legacy consoles with VTS enabled. From now I'll only rely on cmd.exe and conhost.exe in Windows and gnome-terminal in WSLg, where the existent code NetDriver works as expected.
