Yes, it could be a race condition inside libX11. I know libxcb is designed to not have globals, but I am not so sure about libX11. libxcb's .data + .bss is a mere 0xa8 bytes, while libX11's is 0x38e8. That's a lot of global data. So it's entirely possible that GDK isn't getting the reply it needs because that reply was sent to our Display and connection and thus handled by our thread. -- Thiago Macieira - thiago.macieira (AT) intel.com Principal Engineer - Intel DCAI Fleet Engineering and Quality
