When I press Alt in Gedit, and hold it for two seconds or so, the mouse cursor disappears, and then as I continue moving the mouse, the cursor starts flickering. The flickering happens only inside the writing area.
If I short press it, the HUD is activated, and the flickering is not.
Even when I release Alt, the cursor is still flashing, until I:
- change focus to some other app by clicking on it and then switch back to Gedit
- start dragging the window by its border
- press Alt again
Ubuntu version: 14.10.
This doesn't happen on my laptop which has the same software versions.
What's going on and how can I get it back to normal?
