Seems like with the latest VS Code update, all the comment font style has gone Italic. Does anyone know how to change the font back to normal? Thanks.

Easiest way is set in your settings:

"editor.tokenColorCustomizations": {"comments": {"fontStyle": ""}} Other possible way with more controls is Cmd+Shift+P -> Select Developer: Generate Color Theme From Current Settings. Then edit what you need, save it to new theme and load/activate it.
