Update: the app running in Unity7 screenshots is running from QtCreator using the "Desktop Kit" which is provided by Ubuntu SDK IDE. That means, it's using Qt5.4.2 (doublechecked using lsof -p , gotta love that command!) For that reason, I think the problem we have in Xenial is not coming from t

That's a very good point. The issue is not nearly as bad on Vivid+PPA (my laptop), but there are so many differences with Xenial that it's hard to point out the faulty package (although it could be Qt). This needs more investigation, but I can't spend more time on this now... -- You received thi

Let's be clear though, the issue seen on xenial and qt5.5 is _not_ reproduced on 15.10. There is a real regression in text rendering on xenial that the MR is not meant to fix. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bug

My understanding is that Qt's distance field approach to font rendering does not do grid-fitting of characters. So for small font sizes on low- dpi screens, font characters can be poorly antialiased, with 1-pixel wide aspects of the character being rendered between pixels. Distance field text is f
