            Bug ID: 90202
           Summary: Firefox nightly hangs with accelerated layers and
                    latest r600 driver
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: ernstp@gmail.com
        QA Contact: dri-devel@lists.freedesktop.org

(This is not #81680 btw, this is separate...)

If I enable layers.acceleration.force-enabled in Firefox nightly,
Firefox always hangs after a little while of browsing.
This is a regression somewhere, this worked during a couple of months...

I guess this is the GL related stuff in the backtrace. Something DRI3 related?

I have tested with the Radeon driver using both DRI2 and DRI3 btw, it happens
in both cases. The backtraces are when using DRI2.

What do you mean by that? As you pointed out yourself in comment #3, that
backtrace is clearly from running with DRI3 enabled.

I can't seem to reproduce this (with radeonsi). Does it still happen with
libxcb 1.11.1 or newer, and current versions of Mesa and xserver?

Looks like 1.11.1 is in Ubuntu Xenial, should be easy to test on Wily also...
