Every time I attempt to generate a report from the dashboard, the errors below pop up and kibana restarts.

Can you try to switch to chromium browser and see if it works?

```auto
xpack.reporting.capture.browser.type: chromium
xpack.reporting.capture.browser.chromium.disableSandbox: true

```

I think sandboxing doesn't work on centOS 7, so the above will turn that off too.

Not sure if it'll make a difference since the error is coming out of the png library, but worth a shot. There are some issues with Phantom and it will be deprecated once we officially switch to Chromium.

I added those lines ( actually tried this already, uncommented them). I get the same error and Kibana crashes/restarts.

Whats on the dashboard? Does it work for an empty dashboard? A dashboard with a single bar chart? How about if you try generating a report from the visualize app?

Are you doing the print or preserve layout option?
