[Desktop-packages] [Bug 1536751] Re: Font/text rendering is irregular and not pixel-aligned on low DPI screens
I can now see part of the problem more clearly. If you look at labels that contain the same letter multiple times like "Calculator" or "Security & Privacy", then it becomes apparent that the clarity of that same letter changes depending on where it is in the word. Given that Qt caches individual glyphs (discovered in bug 1583088), this variation in clarity should never happen. Most likely the problem is Qt's text rendering is failing to place some glyphs at integer x locations, which is a big deal on regular low DPI displays. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to fontconfig in Ubuntu. https://bugs.launchpad.net/bugs/1536751 Title: Font/text rendering is irregular and not pixel-aligned on low DPI screens Status in Canonical System Image: Confirmed Status in QtMir: New Status in fontconfig package in Ubuntu: Incomplete Status in freetype package in Ubuntu: Incomplete Status in harfbuzz package in Ubuntu: Confirmed Status in qtbase-opensource-src package in Ubuntu: Incomplete Status in qtdeclarative-opensource-src package in Ubuntu: New Status in ubuntu-font-family-sources package in Ubuntu: Confirmed Status in ubuntu-ui-toolkit package in Ubuntu: Confirmed Status in unity8 package in Ubuntu: Confirmed 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 0.4.7+16.04.20160104-0ubuntu1 As you can see from the screenshots the text has low details and, in the case of indicators descriptions at the top, almost disappears.

[Desktop-packages] [Bug 1536751] Re: Font/text rendering is irregular and not pixel-aligned on low DPI screens
@Daniel: I think font hinting is disabled by default for QML Text elements, because Text uses distance fields rendering by default (more info at http://blog.qt.io/blog/2011/07/15/text-rendering-in-the-qml-scene-graph/ ) That was changed in the Label component of our UI toolkit so that it uses "NativeRendering" when the Grid Unit is <= 10, distance fields otherwise.

Just noticed this bug again, now in System Settings. On Unity7 it's perfectly clear (sub-pixel RGB) but in Unity8 it's slightly blurry (greyscale is used). So that's the first part of the problem. The second part of the problem is that Unity8 (especially in the indicator pulldown) failing to apply a nice hinting setting to make the glyph curves aligned to pixel boundaries more often.

[Desktop-packages] [Bug 1536751] Re: Font/text rendering is irregular and not pixel-aligned on low DPI screens
I can't think of anything relevant changed in Qt itself since 5.5.1 landed in xenial in December, so it must have been some other package. You may want to test Qt 5.6.0 to see if that gives any further improvement https://wiki.ubuntu.com/Touch/QtTesting The current plan would be to have Qt 5.6(.1) in xenial-overlay eventually. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to fontconfig in Ubuntu. https://bugs.launchpad.net/bugs/1536751 Title: Font/text rendering is irregular and not pixel-aligned on low DPI screens Status in QtMir: New Status in fontconfig package in Ubuntu: Incomplete Status in freetype package in Ubuntu: Incomplete Status in harfbuzz package in Ubuntu: New Status in qtbase-opensource-src package in Ubuntu: Incomplete Status in ubuntu-font-family-sources package in Ubuntu: New Status in ubuntu-ui-toolkit package in Ubuntu: New Status in unity8 package in Ubuntu: New 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 0.4.7+16.04.20160104-0ubuntu1 As you can see from the screenshots the text has low details and, in the case of indicators descriptions at the top, almost disappears.

[Desktop-packages] [Bug 1536751] Re: Font/text rendering is irregular and not pixel-aligned on low DPI screens
Reopened again. Although the situation definitely got better at the start of April, font rendering in Unity8 still looks quite poor when compared to Unity7. The problem might just be misaligned textures like Unity8 bug 1510382. ** Changed in: harfbuzz (Ubuntu) Status: Incomplete => New ** Changed in: ubuntu-font-family-sources (Ubuntu) Status: Incomplete => New ** Changed in: ubuntu-ui-toolkit (Ubuntu) Status: Incomplete => New ** Also affects: qtmir Importance: Undecided Status: New ** Also affects: unity8 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to fontconfig in Ubuntu. https://bugs.launchpad.net/bugs/1536751 Title: Font/text rendering is irregular and not pixel-aligned on low DPI screens Status in QtMir: New Status in fontconfig package in Ubuntu: Incomplete Status in freetype package in Ubuntu: Incomplete Status in harfbuzz package in Ubuntu: New Status in qtbase-opensource-src package in Ubuntu: Incomplete Status in ubuntu-font-family-sources package in Ubuntu: New Status in ubuntu-ui-toolkit package in Ubuntu: New Status in unity8 package in Ubuntu: New 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 0.4.7+16.04.20160104-0ubuntu1 As you can see from the screenshots the text has low details and, in the case of indicators descriptions at the top, almost disappears.

[Desktop-packages] [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. ** Also affects: ubuntu-ui-toolkit (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to fontconfig in Ubuntu. https://bugs.launchpad.net/bugs/1536751 Title: Font/text rendering is irregular and not pixel-aligned on low DPI screens Status in fontconfig package in Ubuntu: Incomplete Status in freetype package in Ubuntu: Incomplete Status in harfbuzz package in Ubuntu: Confirmed Status in qtbase-opensource-src package in Ubuntu: Incomplete Status in ubuntu-font-family-sources package in Ubuntu: Confirmed Status in ubuntu-ui-toolkit package in Ubuntu: New 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 0.4.7+16.04.20160104-0ubuntu1 As you can see from the screenshots the text has low details and, in the case of indicators descriptions at the top, almost disappears.
