           Summary: CubeStorm hack from XScreenSaver freezes X
           Product: Mesa
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: critical
          Priority: medium
         Component: Drivers/DRI/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: jlp.bugs@gmail.com


I have a HP Compaq nx6325 laptop with integrated graphics (RS482) and
XScreenSaver 5.10. When I open the screensaver settings in KDE 4.4.4 and select
the Cube Storm hack from the list X freezes. I can still SSH from another
machine, but on the laptop keyboard stops responding too. I'm using the Gallium
r300 driver (couldn't find a special component for it, hope this one is oK).
Mesa is from git, pulled on 2010-06-14.

I've now also tried on another computer with RV350 AR chip and I also get the
freeze. I've also tried to run the hack directly with the same results. BTW,
with classic r300 driver all is fine.

Bisected. The first bad commit which locks up:

commit bd1ce874728c06d08a1f9881f51edbdd2f1c9db0
Author: Chia-I Wu <olv@lunarg.com>
Date:   Mon Mar 8 22:19:48 2010 +0800

    st/dri: Switch from st_public.h to st_api.h.

    This is tested with demos found in progs/demos.  However, only the DRI2
    path is tested.

From the branch (which has been merged to master): gallium-st-api-dri
http://cgit.freedesktop.org/mesa/mesa/log/?h=gallium-st-api-dri

If I go one commit back, cubestorm works. It's quite a large commit and it's
not clear to me what the commit does in terms of functionality.

BTW, cubestorm is a single-buffered application.
