[Bug 1446639] Re: Ubuntu loads configuration incorrectly on high-dpi screen

 

This is happening regularly during the first boot(s) after kernel or
xorg updates. Is it possible it could be related to something like
ureadahead?

Title:
  Ubuntu loads configuration incorrectly on high-dpi screen

Status in unity package in Ubuntu:
  New

Bug description:
  When booting, unity loads the desktop partially with double the
  correct size (default setting: scale factor 2, but it loads as if
  scale factor 4). The launcher, dash, application switcher appear too
  big while the panel and applications themselves have correct size.

  After some seconds the screen turns black, the wallpaper appears 4
  times and then the wallpaper appears at correct size as well as
  launcher, dash, application switcher and panel. However, the desktop
  icons and the window content of gtk3 applications appears too small
  (as with scale factor 1). This is only true for gtk3 applications, not
  gtk2, Wine, XUL, Qt, VCL. Also, unity panel uses incorrect (strong)
  font hinting while font hinting is correct in the rest of the system.
  Unity dash uses partially a fallback sans serif font instead of Ubuntu
  font and incorrect character kerning.

  This is similar as bug #1398208.
