$ dpkg-query -W libgtk2.0-dev libxtst-dev libglib2.0-dev libgtkglext1 libx11-dev
libglib2.0-dev 2.32.4-0ubuntu1

libgtkglext1 1.2.0-2fakesync1
libx11-dev 2:1.4.99.1-0ubuntu2.2
libxtst-dev 2:1.2.0-4ubuntu0.1


For comparison:
glib2 2.38.2-1
gtk2 2.24.22-1
gtkglext 1.2.0-9
libx11 1.6.2-1
libxtst 1.2.2-1

Well, downgrading core packages like that would likely be a nightmare (dependencies, dependencies) and I can't get a stack trace, since adding --sync throws a logic_error, based on that bug you linked previously. Looks like I'm stuck.

I have the same issue with mouseovers crashing CEF. I can reproduce the issue on Ubuntu 12.04 32-bit using cef_binary_3.1547.1551_linux32_client (version used by cefpython-29.2) as well as with cef_binary_3.1720.1548_linux32_client (current trunk).

However, I have no problems at all on my dev environment of Ubuntu 13.10 64-bit.

$ DISPLAY=:0 ./cefclient --off-screen-rendering-enabled --url=http://tests/other_tests
[0108/144904:INFO:gpu_info_collector_x11.cc(80)] NVCtrl extension does not exist.
The program 'cefclient' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadValue (integer parameter out of range for operation)'.
(Details: serial 735 error_code 2 request_code 94 minor_code 0)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)

Any link whatsoever causes it to crash, even the links on the built-in tests page. In my application, I am working around this issue by not passing any mouse move messages to CEF - it no longer crashes. Also, this seems to happen solely in offscreen rendering mode. Without '--off-screen-rendering-enabled' cefclient does not crash - however, my application uses Kivy and cefpython, and must use offscreen rendering.

Hello,

I encounter the same issue :
ArchLinux x64
libcef.so #1750 x64

Does someone have any new information about this issue?
I'll let you know if I find something.
