Thanks. I'm definitely interested to know what was causing. Just to be
sure that we can avoid it in the future. Also please report any other
problems or oddities if you encounter them (preferably to the
bugtracker, and not to this mailing list). Using irc is also fine for
quick questions, but my presence may be limited at the usual office
hours or in the middle night (European time).

It may seem that I have some prejudice against Mer, but have a look at
this relatively recent bugreport for example:
    https://github.com/ssvb/xf86-video-fbturbo/issues/25
Nothing can be ruled out and it is difficult to make any assumptions
about what could be possibly wrong in the user's system.

There is one more thing that may be relevant for you. The old r3p0
version of the mali blob can't fully utilize both pixel processors
of the Mali400 MP2. So the performance is not optimal on Allwinner A20.
It is possible to upgrade to a newer version r3p2-01rel2 of the blob to
get better performance, but I was not very sure about it without a good
justification (like somebody having a real use for OpenGL ES and
able/willing to report bugs):
    http://thread.gmane.org/gmane.comp.hardware.netbook.arm.sunxi/4676
Also blobs are a temporary placeholder solution until we get free
open source drivers. Investing extra efforts into getting blobs
running may be counter productive at this moment.
