Title:
  Display size detected incorrectly

Status in mutter package in Ubuntu:
  Expired
Status in qtbase-opensource-src package in Ubuntu:
  Expired

Bug description:
  My external monitor is detected as 7" although it is 32". All
  applications which use Qt auto scaling have huge controls!

  It seems like many users have the same problem
  (https://ubuntuforums.org/showthread.php?t=2390362) and thus disable
  Qt auto scaling. I think the solution should be to fix the size
  detection instead.

  It seems not related to the display server, compositor or window
  manager since the problem appeared in Ubuntu 17.04 (Mir, Unity) as
  well es 18.04 (Mutter, Gnome). I tried it with both Wayland and X (on
  Wayland).

  Further, it seems not related to graphics driver, since I personally
  use the open source driver with my internal Intel card, whereas
  someone else uses a proprietary Nvidia driver
  (https://askubuntu.com/q/1066879/206608).

  If it is in the wrong category, please move it / add the corresponding
  packages.

  If you need any further information to tackle the problem, just tell me!
