Created attachment 72907 [details] 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)
Created attachment 72908 [details] Screenshot, MSAA 2x. 2D image (and text) rendered correctly.
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.
Did you turn MLAA on?
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.
