[Bug]: Malformed pdfs

[shipupi]

What happened?

My project is running on 2 different servers, both running on docker apparently all in same environment. One of them creates pdfs without issue, the other one starts spouting gibberish on the pdfs:

I've done some debuggin and it gets a bit weirder, i've been testing with these two lines:

Pdf::html('<h1>Hello world!</h1>')->disk('tmp', 'public')->save('hello7.pdf');

Pdf::html('<h1>Hello world!</h1>')->save('/var/www/html/storage/app/tmp/hello4.pdf');

Disk() one seems to be behaving more poorly, and never works. The straight save() only seems to work if I run ob_clean() beforehand. But I get some other weirder behaviour, sometimes by saving hello4.pdf, I get a hello5.pdf file created as well (probably from some earlier test attempt, maybe got cached or something?).

How to reproduce the bug

Pdf::default()
->withBrowsershot(function (Browsershot $browsershot) {
    $browsershot->noSandbox();
});

Pdf::html('<h1>Hello world!</h1>')->disk('tmp', 'public')->save('hello7.pdf');
