My Wordpress Dashboard is suddenly quite buggy. To be specific just the admin menu is buggy. When I navigate somewhere in admin area some of the menu items disappear as you can see on the following screen.
After I move mouse over the menu some items re-appear but not correctly positioned as you can see on the next picture (see Updates text).
After I reload the page once or twice (reloading the same page, not navigating somewhere else) or Collapse and Expand menu again menu is fixed.
I don't use any plugins. I have tried to update Wordpress (manually) but it didn't help. I am currently using Wordpress 4.3, Google Chrome 45.0.2454.85 (Official Build) (64-bit), and Ubuntu 15.04.
I have just tested FireFox and there seams to be everything OK so it seams to be something with Chrome, but when I've checked console (in Chrome) there are no errors. The errors might have something to do with Chrome recent update.
