Hi pal,
With the 0.4.5 update, the output should no longer be gibberish, no matter if the text is rotated or not. However, I have unfortunately still not enabled rotated texts visually due to the complexity it adds. I hope to finish that by the 0.4.6 release on Sunday.
Let me know if it works better for you now, and please try it on a text that is completely horizontal too. Thank you!
