关于normal_estimation_using_integral_images.cpp中viewer.spinOnce()执行失败的求助

Hey everyone, I'm running into a frustrating issue while testing the normal_estimation_using_integral_images.cpp sample from the Point Cloud Library (PCL).

The viewer window pops up and displays the point cloud with normals for roughly one second, then immediately crashes. The failure occurs right at the viewer.spinOnce() line within this loop:

while (!viewer.wasStopped ()) {
    viewer.spinOnce ();
}

Here's the error output I'm seeing in my terminal:

X connection to p% broken (explicit kill or server shutdown).
[1] + Done "/usr/bin/gdb" --interpreter=mi --tty=${DbgTerm} 0<"/tmp/Microsoft-MIEngine-In-ceuxubyq.vps" 1>"/tmp/Microsoft-MIEngine-Out-iriujkvs.ttm"

I've already verified that my PCL installation is up-to-date, and dependencies like VTK are properly installed. I'm stuck on figuring out why this crash is happening so abruptly. Any help, troubleshooting steps, or insights would be huge—thanks in advance!
