VSCode UI: wierd white line in certain window height

[Colin-XKL]

Type: Bug

When resizing the height of vscode window, sometimes there is a white line at the bottom of the remote dev icon. Check the screenshot below, it's much more clear than text. I've seen this wierd white line in all vscode releases in the past two months. The bug may had been there for a long time, Tested Platform: Mac OS

@Colin-XKL HI, It's just a border design that happens when you adjust the height of your vscode editor.

Nothing to worry about in your coding :

Similar thing for me, white line is present consistently on 125% and 175% zoom level in vscode.dev. Very annoying on the dark theme.

Maybe this is related to float rounding somewhere?

The issue is recent (probably from 1.80.x).
