[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called

This isn't a Mali error - it looks like your usage of X is failing before you even reach OpenGL ES.

HTH,

After search I found that

Issue: The Mali userspace blob (libMali.so) has issues with threading. It uses threading internally but doesn't call XInitThreads early, which leads to problems.

or because all multithread Xorg application need call XInitThreads before any work with Xorg. libMali implicitly uses threads and call XInitThreads too later.

But how resolve that issue for Orange Pi 2 (Allwinner H3) without direct patching LibMali.so

After debugging es2_info I fount that crash after call XCloseDisplay().
