Hey, thanks for the report. This looks like a known issue with GPU rendering on Windows.

Try this workaround:

Option 1 (recommended, permanent fix):

  1. Create this file: %AppData%\Cursor\User\argv.json
  2. Add this:
{
    "use-angle": "gl"
}
  1. Restart Cursor

Option 2 (quick test):
Run from Command Prompt:

"C:\Program Files\Cursor\Cursor.exe" --disable-gpu

If Option 2 helps, Option 1 should give better performance.

Option 3 (if it still doesn’t work):
Full cache cleanup (make a backup first):

  1. Close Cursor
  2. Win + R → type %APPDATA% → delete the Cursor folder
  3. Win + R → type %LOCALAPPDATA% → delete the Cursor folder
  4. Reinstall from Download · Cursor

Also:

  • Update your GPU drivers (Nvidia/AMD/Intel) to the latest version
  • If it still doesn’t help, please share your GPU model and Windows version (Settings > System > About)
