Ok, VMWare is setting the current crtc mode at a generic 800x600, which isn't
in the list of modes for the connected display. Only approach I see is to
compare the mode name with "preferred", for which I see prior art:
https://github.com/wayland-project/weston/blob/master/compositor/main.c#L1068
Problem is that the "real" KMS platform is unable to determine the
current mode when running on VMware, leaving the current_mode_index at
an invalid value of UINTMAX, which is being passed through to the nested
platform.

I have Qt configured (in QtUbuntu/QtMir) to use multi-threaded GL

As workaround, I can add code to QtUbuntu/QtMir use single-threaded GL

If this is easily reproduced, can you try

@vanvugt - yep it's not ideal. For phone/tablet, to make device rotation

I'm looking into this now. I took an api trace of some simple font

@kgunn - yes I can reproduce it quite reliably too. No need to try the
glyph cache workaround thing, I checked it and it had no impact.
@duflu - Qt is rendering the text.
Since Qt renders text ok in Unity7, there must be some GL configuration
problem in QtMir/QtUbuntu causing this kind of issue.
I've a bunch of questions. Any time you see EGL complaints, it is often
down to the graphics driver.
1. is this complaint for an NVidia-based system only? The log indicates
it has the proprietary nvidia driver installed, which Mir does not
support (and so Unity8 does not run). How are you
