Some drawing tasks, for example recursive fractal drawing are limited by the low resolution of LibreOffice drawing area. It would be fine to extend the precision of the turtle moving, based on more precise position and rotation.
Hello László Németh, Thank you for reporting the bug. Please attach a sample document, as this makes it easier for us to verify the bug. I have set the bug's status to 'NEEDINFO'. Please change it back to 'UNCONFIRMED' once the requested document is provided. (Please note that the attachment will be public, remove any sensitive information before attaching it. See https://wiki.documentfoundation.org/QA/FAQ#How_can_I_eliminate_confidential_data_from_a_sample_document.3F for help on how to do so.)
@Sophie Sipasseuth: thanks for your feedback! I assign myself to the issue, and plan to fix in the next months. More information: LibreLogo uses the position of the turtle shape (with minor refinement during extending a line), which is in twip (1/20 pt), but huge amount of small rounding errors can create a visible problem during turtle moving.
