I'm not quite sure what QtMir is doing to trigger this. I've tried hacks to Mir directly to try and emulate what it might be doing, but my hacks result in nested servers starting and running perfectly still. Something about QtMir I'm failing to emulate... ** Tags added: nested -- You received

Tested with mir-demos on the affected machine. Nesting works just fine with the mir-demos. This bug then is just Unity8/QtMir choosing EGL config modifications that i945 systems can't support. Looking at the QtMir code, I would hazard a guess that the request for 8 bit stencilling is
