Hi Yakui. I created a simple standalone test application that can reproduce crashing very easily for my setup. Letting it run for about a minute (13000 iterations) will run into the crash. I posted the application source as an attachment to a bug I just filed: https://bugs.freedesktop.org/attachment.cgi?id=110316 Here is the bug: https://bugs.freedesktop.org/show_bug.cgi?id=86913 Hope this helps to narrow it down. Please let me know if there's more I can do to help.
