[Bug 1536751] Re: QML Unreadable small fonts on 1366x768 screen


The possible suspects below, from qtbase build dependencies.

package       |  vivid                        | xenial
fontconfig  | 2.11.1-0ubuntu6   | 2.11.1-0ubuntu6 
freetype     | 2.5.2-2ubuntu3.1  | 2.5.2-4ubuntu2 
harfbuzz     | 0.9.37-1                  | 1.0.1-1build2 

harfbuzz could be the most likely suspect. However, also wily has
1.0.1-1build2 - could you test the issue on wily? If it's broken there
too, I could try to help by forward-porting old harfbuzz to xenial. But
if it's not broken there, then it's probably not harfbuzz and also not
freetype or fontconfig (same versions in wily and xenial of all them).

Bug description:
  This is a Dell Vostro 3550 laptop with a fresh install of 16.04 and
  unity8 Mir session

  the version of qtdeclarative5-qtmir-plugin is

  As you can see from the screenshots the text has low details and, in
  the case of indicators descriptions at the top, almost disappears.

  The text could be fixed by using Text.NativeRendering instead of Text.QtRendering for the QML labels on low dpi screens, although text doesn't seem to be the only issue here. The icons are definitely lacking detail as well (QML Image's smoothing is enabled maybe?).
  Also the dots of the infographic don't look like circles at all, they're missing pixels and many of them look like a C more than an O.

  It looks to me like something is setting the wrong resolution, because
  it looks quite bad. But the screenshots are 1366x768 so I think that's
  not the case.

  NOTE: Unity7 looks perfectly fine and detailed
