Blurry flipped cursor on line number

[MrConnorKenway]

• VSCode Version: 1.40.1
• OS Version: macOS 10.15.1

Steps to Reproduce:

1. Change the color theme to a dark theme
2. Move the mouse cursor to the line numbers
3. The mouse cursor blurs and it looks quite different from the system's default mouse cursor

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

Or maybe you can offer an option to disable the flipped cursor feature to solve this issue?

@misolori Here is the CSS we have for the inverse cursor on macOS:

vscode/src/vs/editor/browser/viewParts/lineNumbers/lineNumbers.css

Lines 29 to 34 in ff7e302

	.monaco-editor.mac .margin-view-overlays .line-numbers {
	cursor: -webkit-image-set(
	url('flipped-cursor-mac.svg') 1x,
	url('flipped-cursor-mac-2x.svg') 2x
	) 24 3, default;
	}

@alexandrudima what was the rationale for flipping the cursor in this instance? I always thought it was a bit odd.

[alexdima]

I think we took it from Visual Studio or from Word, not 100% sure...

@alexandrudima @rebornix what do you think about making this a regular cursor: pointer on hover instead of using a custom one? This would match all of our other hover cursors in the gutter:

@misolori We can try removing the flipped cursor, but I wouldn't make it a hand/pointer, I would just leave it as is... Having it be a pointer over the line numbers feels weird to me.

[miguelsolorio]

I'm ok with the default cursor as well, the pointer was mostly to indicate that you can select an entire line.

This now uses the default cursor (non-flipped) when hovering over line numbers:
