解决方法是利用屏幕播放功能，并在出现问题时保存最后一帧（或几帧）：

package main
import (
    "context"
    "encoding/base64"
    "fmt"
    "os"
    "github.com/chromedp/cdproto/page"
    "github.com/chromedp/chromedp"
)
func main() {
    ctx, cancel := chromedp.NewContext(context.Background())
    defer cancel()
    var screenshot string
    chromedp.ListenTarget(ctx, func(ev interface{}) {
        if ev, ok := ev.(*page.EventScreencastFrame); ok {
            // Only keep the last frame.
            // You can modify the code to keep several frames or all the frames.
            screenshot = ev.Data
            go func() {
                _ = chromedp.Run(ctx, page.ScreencastFrameAck(ev.SessionID))
            }()
        }
    })
    if err := chromedp.Run(ctx,
        page.StartScreencast(),
        // Put your actions here.
        page.StopScreencast(),
    ); err != nil {
        if screenshot != "" {
            buf, err := base64.StdEncoding.DecodeString(screenshot)
            if err != nil {
                fmt.Printf("failed to decode the screenshot data: %v\n", err)
            } else {
                _ = os.WriteFile("screenshot.png", buf, 0o644)
            }
        }
        panic(err)
    }
}
