Text colors in editor sometimes randomly change when scrolling

Issue Description

When editing code in an editor window, on very rare occasions, the text coloring that is based on the code content type will randomly change as you scroll down the page. To demonstrate the effect I created a bunch of comment lines between my code.

Other notes:
The Minimap shows the same coloring. There also appears to be 'ghost' characters in it.
The formatting is preserved if copied and pasted into another program, a new message in Outlook for example.
Closing and re-opening VSC fixes the issue.

Another person reported the same issue before and it was closed and suggested to be moved here: https://github.com/microsoft/vscode/issues/120800

Visual Studio Code Extensions

Inizia riproducendo il problema in Visual Studio Code 1.55.2 su Windows con l’estensione PowerShell, scorrendo un file contenente molte righe di commento. Analizza la colorazione della sintassi dell’editor e il comportamento della minimappa; l’attività è completata quando lo scorrimento non cambia più i colori del testo né produce caratteri fantasma, mentre il contenuto copiato rimane corretto.
