Title:
  UI scaling inconsistent when using new display scaling option

Status in xorg package in Ubuntu:
  Confirmed

Bug description:
  Just installed Ubuntu 14.04 on a Lenovo Yoga 2 Pro, which has a
  3200x1800 display. Consequently, I need to scale up everything in the
  system to have anything render at a reasonable size. I found the new
  "Scale for menu and title bars" option in the Display Settings, and
  set it it 2.25. This, for the most part, did what I wanted.

  * Unity interface is scaled
  * Text is scaled
  * Many builtin applications seem to scale correctly 

  However, there's some funky inconsistencies as to what has scaled:

  * Depending on what the mouse is over, it either renders at the larger (correct) size, or a smaller (incorrect) size. Examples of things which render the mouse incorrectly include the global/window bars, unity application selector, most applications (firefox and most of software center are notable exceptions), and sometimes right-click menus.
  * Some (GTK provided?) widgets (most notably checkboxes, radio buttons, scroll bars, and ) render too small. This is visible in most third-party applications, which are otherwise correctly sized. Firefox and CompizConfig are examples of this, even after layout.css.devPixelsPerPx was changed in Firefox to match the display setting.
  * The change occasionally doesn't correctly register with some or all applications (regardless of whether they were open at the time). Adjusting the slider always changes the unity global ui correctly, but sometimes the settings manager or nautillus would not actually render at an increased size, even after a reboot. Other times it would register fine even without a reboot.
