Comment 1 for bug 1387219

After typing the text, selecting it, and copying it with Ctrl+C, I did experience a similar issue.

The gedit cursor did disappear, but I think that's normal - it disappears when you select text.

But when I copied the text, the mouse curor disappeared as well, which was not expected. It also started flickering when I moved it. Do you experience this movement-related flickering?

Also, do you experience these issues when long-pressing Alt on the window? When I long-press Alt, the flickering starts as well. If I short press it, the HUD is activated, and the flickering is not.

The flickering stops once gedit is unfocused.

I also documented the bug in this question: http://askubuntu.com/questions/541226/mouse-cursor-dissapears-when-long-pressing-alt-in-gedit.
