Replacing conhost.exe with OpenConsole.exe

[RaXorX]

Describe the problem:
Unofficial and potentially not recommended way to using OpenConsole by replacing it with conhost.exe causes tabby to start lagging and hanging often. This happens during any operations during any time, whether closing the tabs or using tabby, most often that it happened to me was during closing the tabs only.

To Reproduce:
Replace conhost.exe with OpenConsole.exe from windows terminal.
Launch Tabby.
Open a couple tabs and then try closing them.
