No, but let's note that the supplied cairo library in OS4 is totally unaccelerated and even slower than the plain image surface, which is why joerg used a straight cairo recompilation for OWB instead.
I also use my own cairo "port" for OWB MorphOS port and related projects.
Here can also read about problems of OS4 Cairo from a OS4 dev.

The Cairo clipping is so ridiculously slow on OS4 that I'm not able to
fully Cairo-ise it unfortunately,......
""""
And this is the biggest Problem i think is in OS4.
There is a big and lot announcment of OS4 Feature but when you look deeper in it, you notice that it work worser than on other Systems.
sure showing lots feature on paper is maybe good for sell.
But what every future AOS need are more developers.And if maybe a developer buy such a system and he see, its only on paper good, maybe he sell soon his OS4 system because he think the OS4 devs are not qualified ebough to do a attractive System for more Users/dev than Fans that see OS4 as last Hope.
every developer knows its easy to make a software in parts running so its good enough to announce the feature and it is in some way usable.
But if a software should have a future, the software must be rock solid or near rock solid.
Cairo is btw since long time in AROS in and its not so complicate to compile.
But when a program run without Cairo its always faster not use Cairo.
maybe there do somebody a Cairo bench that show speed between MOS and OS4 Cairo and clipping.
Cairo on MOS is opensource, but OS4 devs fiddle it in OS4 so its hard to add a new cairo on OS4.
Waht Cairo Version OS4 have ?
look what Cairo Version OS4 have and look what currently opensource Cairo is here.
and what bugs are since then fixed in opensource Cairo.
same is with other libs, as newlib.OS4 with the closed source strategie have old newlib.

Despite any open status it has (that you guys have been discussing) it has no debug symbols in it. All I found in the binary are errors. And on my system it dates back to 2005!
Is that right? The newest-library in OS4 is four yars old? :-?

And when build a opensource Version, then there can also debug symbols build in to make it more easy to find Bugs
the next thing is the OS4 compositing Engine.Here in Forums can read that it es near unusable slow when a System have only 32 megabyte GFX Card(as micro aone many user have)
with 64 mb it work better, but still can run in some slowdown Problems.so there need at least 128 megabyte to get no large slowdown on compositing in OS4 it seem
I dont know how MOS transparency and shadow work, but i have not read in Forums that it better switch off, on 32/64 meg GFX Cards.
So for my eyes MOS transparency seem better implement.
