Hanging app in shim_glBindFramebuffer() from libMali.so

Hi there,

I have an Android app with 3M+ downloads, and I get frequent 'Application Not Responding' crash reports.

When I examine these, my main thread always hangs waiting for futex in shim_glBindFramebuffer() of libMali.so

What could be causing this call to dead lock?

This is the callstack, identical in all reports. I get 15 reports per day or so.
