            Bug ID: 91930
           Summary: Program with GtkGLArea widget does not redraw
           Product: Mesa
           Version: 11.0
          Hardware: x86-64 (AMD64)
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: pavol@klacansky.com
        QA Contact: dri-devel@lists.freedesktop.org

If the program contains GtkGLArea widget then whole window does not redraw upon
an action (dragging sliders), and redraw can be done by alt-tabing or swapping
workspaces.

This example app shows the defect.

I cant compile older version because of
c61bc6ed844b39e600cc64e3e552c7bf1894d7ba. This one also crashes with software
rendering.

Can you bisect Mesa?

When crossing that commit, you can either fix up
src/util/.deps/libmesautil_la-strtod.Plo manually or clean all build output and
build from scratch.

I started bisect at commit f5c110199675b7f4c50d4a7a64b6aac44c55d0a4, where it
kind of works, i.e. does not crash, but the widgets start to appear only after
redraw (mouse hover or slider moved).

And this is the culprit which makes it segfault (i.e. from kind of working as
above to not working and then it was "fixed" where it does not segfault but
does not redraw either).

The update to mesa 11.0.3 fixed this issue for me.

Anyone else can confirm that this is fixed?

R600 works, llvmpipe does not (draws now, however some parts are black at the
start and drawn only when mouse goes over it).

Can you test with LIBGL_ALWAYS_SOFTWARE=on ? Because I am getting black widget
before I hover over them.
