Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report. Do you have the native titlebar enabled? I tried to reproduce this but couldn’t. Could you also share your Cursor window settings?

[WinnieS0728]

I think I’m using macOS native title bar.
I didn’t setting anything.
how to show you my cursor window settings?

my full screen looks like this.

btw there is a toggle side bar button on the top right tool bar.
is it a button doing same thing?

[deanrie]

Settings in your settings.json related to the window. No, this button opens the list of agents.

[WinnieS0728]

there’s nothing related to window in my user settings.

in my project settings have some color setting witch generate by peacock extension.

Open VSX Registry

{
    "workbench.colorCustomizations": {
        "activityBar.activeBackground": "#9ca5ca",
        "activityBar.background": "#9ca5ca",
        "activityBar.foreground": "#15202b",
        "activityBar.inactiveForeground": "#15202b99",
        "activityBarBadge.background": "#a65968",
        "activityBarBadge.foreground": "#e7e7e7",
        "commandCenter.border": "#15202b99",
        "sash.hoverBorder": "#9ca5ca",
        "statusBar.background": "#7b87b8",
        "statusBar.foreground": "#15202b",
        "statusBarItem.hoverBackground": "#5a69a6",
        "statusBarItem.remoteBackground": "#7b87b8",
        "statusBarItem.remoteForeground": "#15202b",
        "titleBar.activeBackground": "#7b87b8",
        "titleBar.activeForeground": "#15202b",
        "titleBar.inactiveBackground": "#7b87b899",
        "titleBar.inactiveForeground": "#15202b99"
    },
    "peacock.color": "#7B87B8"
}

I remove this file disabled extension and reload window, the toggle button is still behind close button.

maybe you need my mac version?

Oh, sorry, I didn’t notice in your previous screenshot that it seems you don’t have a native titlebar. But the problem might be with one of the extensions. Try booting in safe mode using this command in the terminal: cursor --disable-extensions. You can also open this sidebar using Cmd + Shift + S.

[WinnieS0728]

forgot to mention.
cmd + shift + S have the same keybinding with Save As

so I reassign to ctrl + option + cmd + m witch is unique keybinding.

after all.

open cursor by cursor --disable-extensions or use ctrl + option + cmd + m both not working.

where should this agent list shows up?

I notice that in keybinding page it says Toggle Background Agents Sidebar

I’m not using background agents, is that the problem?

[WinnieS0728]

yes it is.
after I enabled background agents.

the list shows up.
the button is at the right place.

everything working fine.

thank you so much.

maybe we can hide the little button when user is not enable background agent?

[deanrie]

Thank you for the additional info, it will really help us. I think you’re right, hiding the button is a great option.

Also for linux (ubuntu specifically), clicking that button does nothing at all.

[Nick_Radford]

Just ran into this and posted a reply in a related topic, but if you go to Cursor Settings > Beta and toggle Background Agent, then the Toggle Sidebar button is clickable again. Then you can click it to hide the Background Agent pane, then toggle Background Agent off again.

Hey, thanks for the info. Which Linux distribution are you using? Does the shortcut Ctrl + Shift + S open this panel?
