Dear Hans,

not sure I can reproduce exactly your issue, but I noticed that if you move the mouse cursor very slowly from the main categories section to a submenu, you can manage to reach a hitbox that belongs to neither and the submenu closes before you reach it.
I *really* have to do it on purpose though, as soon as the mouse moves at even a moderate pace I can’t reproduce anymore.

> 2. When hover the mousepointer over any of the categories, I see the mouse cursor blinking black and white colour, so as if the mouse is doing something. The mouse is not touched during this.

With the additional issues on the mouse cursor (and the fact that you cannot reproduce on your other machine) this starts looking more like a display driver bug.

Can you see anything interesting in the system’s journal while the issue is happening or some time before ?


Thanks,
