Good morning everyone, this is the first time I write on this mailing list cause \
we're having hard time to figure out an issue with the xorg windowing system; I hope \
this is the right place to ask for help, if it's not I'm sorry; I'd ask in that case \
where to submit this request. It happens that our application sometime get stuck \
calling an X primitive. The premise is that the same identical code has been running \
on a different platform for years (Ubuntu 14.04 with an NVidia video card), while on \
our newest architecture (Ubuntu 16.04 with an Intel video card) the trouble occurs a \
couple of time in a day; the application goes in hang in the context of a call to the \
xcb library while the cpu usage of server X (the Xorg application) raise up to 99-100 \
% !!!. This is the stack trace of the application getting stuck:

This is instead the x server backtrace when the trouble occurs:

The client application has more threads but just one deals with X windows system.
Currently we're trying to install x server version 1.19 instead of the 'original' \
1.18.04 Ubuntu 16.04 ship with (configuring some ppa repo)
Any idea about what could be the reasons of this issue? Thank's in advance
Maurizio
