Editor de Código presenta lentitud al extender el chat de Github Copilot.

[arturocalcaneo]

Type: Performance Issue

El problema se presenta después de realizar una serie de peticiones al chat, cuando son más de 3 la cantidad de referencias y la magnitud de la respuesta.

El editor no solo presenta lentitud en código abierto sino también en ventana del chat de Github Copilot, al navegar por la ventana de directorio y archivos y en los tabs de pestañas de archivos abiertos.. sin importar si se tiene abierto solo un archivo o varios a la vez.

En el párrafo anterior solo se detallo las partes en que se presenta problemas de experiencia, cuyos problemas parecen resolverse de manera temporal usando "Desarrollador: Recargar ventana" con "ctrl + shift + p" en Windows o "Command + shift + p" en Mac.

Title:

Code Editor experiences slowness when expanding the Github Copilot chat.

Body:

Type: Performance Issue

The issue occurs after making a series of requests to the chat, specifically when there are more than 3 references and the response is large.

The editor not only becomes slow in the open code but also in the Github Copilot chat window, when navigating through the directory and files window, and in the tabs of open file tabs—regardless of whether only one file or several are open at the same time.

The previous paragraph only details the areas where user experience problems occur, which seem to be temporarily resolved by using "Developer: Reload Window" with "ctrl + shift + p" on Windows or "Command + shift + p" on Mac.
