[Bug 1536751] Re: Font/text rendering is irregular and not pixel-aligned on low DPI screens
The problem is seemingly reduced in xenial now with the new visual
design. But the problem is not eliminated.
Fonts in the indicator pulldown (on desktop) are still not very well pixel aligned. At a guess, it looks like we might have made any of these mistakes:
(a) Insufficient hinting
(b) Text is pre-rendered in a bitmap whose background colour is different to the final screen.
(c) Text rendering is trying to use sub-pixel alignment, but only getting greyscale on screen (see (b))
Sad to say Unity7 text still looks much nicer.

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
