           Summary: r200 overflow command buffer error
           Product: Mesa
           Version: git
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/r200
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: fred@crozat.net


With Mesa 7.9, on r200 chipset (Radeon 9100 IGP), when using gnome-shell 2.91.0
/ clutter 1.4 (or 1.5.x), I'm getting :

File r200_swtcl.c function r200_swtcl_flush line 309
 Rendering was 7 commands larger than predicted size. We might overflow 
command buffer.

whatever the video memory size (up to 128MB)

this is with libdrm 2.4.22 and kernel 2.6.34 or 2.6.36-rc6

Is this still an issue with mesa from git master or the 7.9 branch?  This patch
