I've just upgraded to a new laptop with Ubuntu 16.04 and installed Vim 7.4 1-1952.

I installed most of my plugins when I noticed that 80% of the time when I press <kbd>F11</kbd> to go fullscreen, Vim doesn't "update"/redraw unless I press a button or click on the screen. Here's a photo of what happens when I press <kbd>F11</kbd>:

I've tried disabling my plugins to see if one of them might be the issue. I realized that this only happens when I have some sort of syntactic-checker enabled such as YouCompleteMe or syntastic.

Again, the issue resolves itself immediately once I press *any* button but I can't figure out what could be causing it. I don't have the same problem anywhere else aside from Vim.
