Thank you for writing.
I have logged an issue on our feedback portal
, here: https://feedback.telerik.com/Project/154/Feedback/Details/239607-fix-radrichtexteditor-the-caret-position-can-be-calculated-more-precisely
. Additionally, you can subscribe to the item and be updated when its status changes. The caret is being created dynamically and due to the nature and complexity of the issue, I cannot suggest a suitable workaround. If it can fit your local setup you can decrease the caret`s width:
.radRichTextEditor1.CaretWidth = 1;
I hope this helps. Let me know if you have other questions.
