Rod Version: v0.116.2

The code to demonstrate your question

Works as expected

func TestRod(t *testing.T) {
	browser := rod.New().MustConnect()
	defer browser.MustClose()

	tests := []struct {
		name  string
		input *rod.Page
	}{
		{
			name:  "1",
			input: browser.MustPage("https://www.example.com"),
		},
	}
	for _, tc := range tests {
		t.Run(tc.name, func(t *testing.T) {
			tc.input.WaitLoad()
			tc.input.Screenshot(true, &proto.PageCaptureScreenshot{
				Format:                "png",
				Quality:               new(int),
				FromSurface:           false,
				CaptureBeyondViewport: false,
				OptimizeForSpeed:      false,
			})
		})
	}
}

Fails

func TestRod(t *testing.T) {
	browser := rod.New().MustConnect()
	defer browser.MustClose()

	tests := []struct {
		name  string
		input *rod.Page
	}{
		{
			name:  "1",
			input: browser.MustPage("https://www.example.com"),
		},
		{
			name:  "2",
			input: browser.MustPage("https://www.example.com"),
		},
		{
			name:  "3",
			input: browser.MustPage(),
		},
	}
	for _, tc := range tests {
		t.Run(tc.name, func(t *testing.T) {
			tc.input.WaitLoad()
			tc.input.Screenshot(true, &proto.PageCaptureScreenshot{
				Format:                "png",
				Quality:               new(int),
				FromSurface:           false,
				CaptureBeyondViewport: false,
				OptimizeForSpeed:      false,
			})
		})
	}
}

What have you tried to solve the question

Didn't look the problem yet. I'm opening the issue to inform you about the problem.
Tested in 0.112.x, 0.115.x, 0.116.0 - all works as expected.

Same issue here, have anyone figured out a work around ?

Also, the instrumented chrome goes to 100% CPU usage, not sure why.

Ok, I just had to relearn how to debug go-rod and chrome.

It seems google-chrome and the more recent chromium version fails if trying to use the GPU.

I fixed by adding the disable-gpu and disable-software-rasterizer flags in my instrumented code:

	...
	var controlURL string
	chromePath, err := exec.LookPath("google-chrome")
	var l *launcher.Launcher
	if err == nil {
		klog.V(1).Infof("Using system's Google Chrome")
		l = launcher.New().Bin(chromePath)
	} else {
		klog.Warningf("Using rod downloaded chromium, with --no-sandbox")
		l = launcher.New().NoSandbox(true)
	}
	controlURL = l.
		Set("disable-gpu", "true").
		Set("disable-software-rasterizer", "true").
		Logger(os.Stderr).
		MustLaunch()
	...
