The position of the Gedit cursor is not visible

[Stefano Dall'Agata]

When I open Gedit the blinking cursor is not visible, it does not appear even when writing and therefore it becomes difficult to correct misspelled words.

I wrote the word "test" twice, and then I clicked twice with the left arrow, positioning the writing point after the "o".
The cursor has never been visible.

[Stefano Dall'Agata (essedia1960)]

The word "prova", sorry.

[Sebastien Bacher (seb128)]

What theme are you using? It seems rather an issue with the color in use, the problem doesn't exist with the default scheme

[Stefano Dall'Agata (essedia1960)]

With "Kate". Ok, in other is visible.

[Stefano Dall'Agata (essedia1960)]

Changing the theme in appearance it looks like the cursor now see also on Kate
