Testing the Open-Source cua-driver: Five GUI Scenarios, Where They Failed, and Workarounds

At a glance

We ran cua-driver, an open-source tool for computer control, on a MacBook connected to an AI agent. We ran five GUI scenarios directly. Several of them got stuck, and we found other routes to get results.

Key points

1. 1

   We tested the computer use feature, where the agent directly operates the screen.

2. 2

   In one scenario, the screen capture tool was denied, so we got the screen state through a different tool.

3. 3

   A text editor window would not open, so we switched to the foreground execution method.

4. 4

   Korean text input came out garbled, unlike what was requested, but interference from the user's own screen activity is now more likely to be the cause.

Why it matters

Knowing where and how AI computer-control technology actually fails helps you spot the risks in advance when using tools like this at work.
