Confirmed even with trunk Xmir... Although Xmir doesn't crash it does show errors with Chromium:

[DRI2] DRI2SwapBuffers: driver failed to schedule swap Looks like maybe Chromium is confused and trying to speak native Mir and X/GLX simultaneously..? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1420959 Title: Xmir (DRI2 mode) crashes when launching chromium Status in xorg-server package in Ubuntu: Confirmed Bug description: I've installed xserver-xorg-xmir, unity8-desktop-session-mir, and set my lightdm seat type to "unity". Using normal everyday unity-greeter and unity7 session with xmir, most things work well. The one thing that doesn't is trying to launch chromium. Doing so takes down the xmir session entirely.
