Strange border - outline on greek characters since v1.63 VS Code

Question

Today I opened Visual Studio Code to continue my project and I realized that almost every Greek character has a border as it is shown in the picture.

• What is this?
• How can I disable it?

Answer 1

These are caused by these unicode highlighting settings that are new to v1.63:

You can try disabling them or you can change the color with these colorCustomizations in your settings.json:

 "workbench.colorCustomizations": {
    "editorUnicodeHighlight.border": "#0000",  // set to transparent
    "minimap.unicodeHighlight": "#0000",
    "editorOverviewRuler.unicodeForeground": "#0000"
}

Answer 2

Replying to myself, i downgraded to 1.62.2 version and everything is back to normal.
