Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the detailed report with logs and repro steps.

This looks like a GNOME-specific issue with how Cursor’s context menu interacts with the shell. The Clutter allocation error with -2147483648 (integer overflow) suggests the menu is getting invalid sizes during rendering.

A couple of workarounds to try:

  1. Try running Cursor with the native title bar. Add "window.titleBarStyle": "native" to your settings.json.
  2. Or try the Ozone/Wayland flags if you’re on Wayland: cursor --enable-features=UseOzonePlatform --ozone-platform=wayland

Which display server are you using, X11 or Wayland? You can check with echo $XDG_SESSION_TYPE.

I’ve passed this to the team. Your logs are helpful for finding the root cause. Let me know if either workaround helps.

Thanks.

I’m sure I’m in X11, and with gnome-shell --version GNOME Shell 42.9 which is matched with ubuntu 22.04 after sudo apt upgrade.

I tried set window.titleBarStyle to native, it worked. But It will change the apperance of cursor. The title bar are splited in two slips :grin: , sense of division discomfort users, so I don’t think it’s the best solution.
