Editor Logs and Xorg

When I open Unity3d on empty or casual project, Editor crash and close itself or work only max a few minutes. I wrote to unity team but they say that is issue with mesa driver. I add 4 logs from unity crash and one from xorg. I think it is something wrong with this lines:

[xcb] Unknown sequence number while processing queue
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.
Unityyy: ../../src/xcb_io.c:259: poll_for_event: Warunek zapewnienia `!xcb_xlib_threads_sequence_lost' nie został spełniony.
