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
