Title:
Changes to support of Gallium 0.4 makes graphics very slow

A change in the last week with automatic updates has changed the support of
Gallium 0.4 on my RS780 chip set to
Gallium 0.4 on llvmpipe (LLVM 3.5, 128 bits). The result is that graphics
response is considerably (visibly) slowed by the introduction of this
interpreter. Further LLVM and its supporting components were not loaded.
One wonders if any kind of testing was done on this anywhere in the
upstream side, or it was just believed that this was "better". I can
assure you it is worse.
The worst effect is on full screen "games". The frame rate has
dropped off to something like one per second or worse when running
with wine. Native mode programs are also noticeably affected, in
particular Libre Office Calc spreadsheets.
I did look up this new approach in so far as I am able using the
synaptic program, and discovered that LLVM was not loaded. Naively, I
loaded it with its related components. There is no visible
improvement.
I need a work-around or a fix for this ASAP. My system is now very
close to disabled.
