Created attachment 133743 [details] Unable to put text in the writer It is impossible to insert text within "text forms" available in the LibreOffice Writer gallery, but this behavior does not occur in Draw and Impress. The idea is to make all the applications of LibreOffice treat the forms of texts of the gallery as they really should be, in this case forms of texts! You must allow applications such as Writer and Calc to insert text within the shapes.
Created attachment 133745 [details] In Draw, you can place text
First insert the image from the Gallery to Draw and then copy&paste it to Writer. After that it is a Draw-image and you can add text. Writer has its own kind of images, which have different properties. It is a long time aim to extend the Draw-images with the properties, currently only available for Writer-images, and then remove Writer-images at all. I will set this issue to "enhancement", but actually a "wontfix" would be more realistic.
