For sure ! You can create an example file like this one: https://github.com/tecnickcom/TCPDF/blob/main/examples/example_066.php If it reproduces the bug you can create a PR for it (and it's fix ?)

Hi, my appologies for not replying ealier The best is to create a pull-request and put the example file in it, the tests will be run automatically And we can discuss on it quicker
