Blinking cursor outline when selecting with mouse

[EugeneDae]

• VSCode Version: 1.43.2
• OS Version: macOS Catalina 10.15.3 (19D76)

Steps to Reproduce:

1. Select text with a mouse and pay attention to the cursor: its outline would repeatedly appear and disappear at the rate of your movement. This doesn't happen in any other text editors and looks ugly.

Cursor with outline:

Cursor without outline:

If you select fast, the transformation happens fast as well, so most users probably don't notice it:

Here's TextMate for comparison — buttery smooth:

Does this issue occur when all extensions are disabled?: Yes

I believe the OS is doing that, but I don't know why.

@alexdima The thin cursor is a custom cursor provided by VS Code:

Disabling this CSS rule fixes the issue for me.

To whoever lands here from Google, if you want to fix the issue described above, install Customize UI extension and add the following to your settings.json:

    "customizeUI.stylesheet": {
        ".monaco-editor.hc-black.mac .view-lines": "cursor: text !important;",
        ".monaco-editor.vs-dark.mac .view-lines": "cursor: text !important;"
    }

I've been using this for a month or so without any issues.

This special cursor came in via #4654 for #754 . It looks like macOS improved (possibly when they added support for dark OS themes?) and now they render a good text cursor by default.

From what I can tell on my monitor and macOS Catalina this now looks good. Adding verified label.
