          Priority: medium
            Bug ID: 59285
          Assignee: dri-devel@lists.freedesktop.org
           Summary: [regression] Non-MSAA no longer working
          Severity: major
    Classification: Unclassified
                OS: Linux (All)
          Reporter: bugspam@moreofthesa.me.uk
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: git
         Component: Drivers/Gallium/r600
           Product: Mesa

Created attachment 72907
  --> https://bugs.freedesktop.org/attachment.cgi?id=72907&action=edit
Screenshot, MSAA disabled. 2D image should not be… blurred.

I've recently tested both Tremulous (GPP) and Unvanquished with a fresh mesa
git build (albeit with one change, ref. bug #53130).

Without MSAA (with r_ext_multisample = 0), a frame or two may be rendered, then
; while much of the rendering is correct, at least some of the text is…
apparently smoothed.

(Linux 3.6-rc7, mesa git 5eeedb852b8a422f31d4d4f018187020c713fffa, libdrm
2.4.40, radeon DDX pre-7.0 git)

For the record, 3D rendering appears fine both with and without MSAA; and I'd
intended to say that, without MSAA, rendering may apparently stop while the
program continues running otherwise normally.

Was on, yes. But that's the first time that I've seen it make any difference,
co-inciding with MSAA being available for use…

Long story short, MLAA is disabled if an MSAA visual is used. MLAA can blur
everything if you enable the MLAA variant that doesn't use a zbuffer.

This is not a bug.
