Title:
  Wrong font scaling with multiple displays

Status in mutter package in Ubuntu:
  New

Bug description:
  I have a laptop with built in display 2560 x 1600 resolution. So for this display I need to set the scaling to 125% otherwise the fonts are too small, practically unreadable. 
  Then, I am connecting external display with resolution 2560 x 1440 for which I want to set the font scaling to 100%.

  Attempting to change the font scales results in:

  - font scaling cannot be set different for each display
  - when the font scaling is set to 100 % it is ok
  - when the font scaling is set to 125 % for laptop (primary) display this affects both displays, the settings form starts to generate artifacts and becomes partially non-responsible (settings need to be restarted)
  - when the font scaling is set to 125% on external display, this leads to improper font scaling (200%)
  - fractional scaling was enabled in all cases

  Summary:

  - non-responsive Settings when font scaling is changed
  - improper scaling on external display
  - scaling cannot be set differently for attached displays
