Description Frederic Crozat 2010-10-06 14:01:45 UTC

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

Comment 1 Frederic Crozat 2010-11-01 05:05:53 UTC

confirming issue with 2.6.36 final kernel, libdrm 2.4.22 and gnome-shell 2.29.1 / clutter 1.5.x

Comment 2 Alex Deucher 2010-11-01 06:08:25 UTC

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

Just tested 7.9 + r200 6936fbc03999354075da4d5b91b1ee7ce190fa80 commit : still no change.

Comment 4 Jerome Glisse 2011-02-09 07:31:58 UTC

Still an issue ?

Comment 5 Frederic Crozat 2011-02-09 07:36:42 UTC

I'll do more tests soon

Comment 6 Frederic Crozat 2011-02-10 22:38:46 UTC

tested with 2.6.37 + Mesa 7.10, still an issue

Comment 7 Frederic Crozat 2011-02-10 22:39:12 UTC

(and libdrm 2.4.23)
