That was 'fixed' with what looks like a temporary release with many
graphical issues, probably for those who rather have an upgraded xorg
able to actually render something with nvidia drivers for developing
reasons than a fully working xorg... Which makes other things, such as
gui testing, pretty hard...
The nvidia driver still doesn't support the new xorg abi (not
fully, although they claim so, most features aren't actually working),
that's the main reason of the new issues coming out.

They probably already know about this:
The problem here is that as for that post on nvidia forum, they said it
could be a bug in xorg's abi. Yet it could actually be a feature. So
nvidia released a not-fully-working driver that notfully-supports
xorg's new abi... So what now? It's either a xorg bug for having broken
abi, or a nvidia bug for not being able to support the new abi...
Opening a bug for any of them would probably end in a mutual blame...

Mh.... I actually tried upgrading again today to run
nvidia-bug-report.sh, but I wasn't able to reproduce it either... Dunno
what to say here, yesterday I did several tries, and it only worked
after removing ignoreABI false... Got to apologize about that, probably
there was something else in the way

I know that. Yet it's useable thanks to stuff like apt-listbugs, and
I'm not really complaining about that. I just don't see why it's
considered better to include a not fully working (and older)
nvidia driver to fix this issue, when it just causes a good lack of
performance (and it's probably just a workaround until a real solution
is found)... I mean, it's new xorg vs new nvidia (since the 'new
driver' is actually a patched old release), woudln't it be better to
leave things as they were (or, at least, warning about the possible
performance lost when upgrading) until nvidia/xorg come to a really
working solution?
