I'm looking into this now. I took an api trace of some simple font rendering by Qt on Mir showing the problem, and executed it on my X11 session. It renders ok on X11. Reading through the apitrace, Qt seems to be doing the right thing.
I suspect the mismatch we have between Mir creating a GLES context and Qt expecting a GL context is hitting us here. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity8 in Ubuntu. https://bugs.launchpad.net/bugs/1583088 Title: Randomly corrupt font / text / characters in Unity8 Status in Canonical System Image: Confirmed Status in gnome-desktop package in Ubuntu: Invalid Status in qtmir package in Ubuntu: Confirmed Status in unity8 package in Ubuntu: Confirmed Bug description: Corrupted characters in text rendering, mainly in Unity8 window titlebars.
