Bug#486507: libx11-6: Locking assertion failure with vmware-server-console
Hi XCB list,
it seems that there's a bad interaction between Xlib/XCB and vmware,
that leads to assertion failures inside xcb_lock.c, even with sloppy
locking enabled. The backtrace below points to libXrender, but seems to
also happen using the system libXrender.
This is with libX11 1.1.4 and libxcb 1.1.
Thanks,
Julien
