still looks ugly but there is no error message anymore.
and it flashing black when i resizing its window, text itself is not resizing
but it's there. probably just redrawing itself that ugly.

OpenVG is still being actively developed. I can't say if this bug should be
attributed to us (r300g) or the state tracker (st/vega). I need some clue as to
what is wrong there. Have you tried the softpipe driver?

I've just had a look at st/vega source code and found a shader which can't run
on DX9-class hardware, like r500 and nv40. The shader in question is
"convolution_asm" in asm_filters.h. The presence of ARL makes it require
DX10-class hardware but the loop and break instructions are not nice either
(not supported in shader model 2.0).

i don't know how it should look either :) i just know that before this patch
and recent big changes it was just ugly black stuff in ugly white box.

we should probably ask someone who wrote those demos.
is it possible to use different gallium driver on-the-fly without X restart,
library rename, etc. ?

if it should look like it looks on recent screenshots then this is, probably,
_fixed_.
on r600g (R770) those demos were outright segfaulting before openvg 1.1 bump
and now they look indistinguishable from those last r300g screenshots with 2
exceptions though: 
1) lion rotating much slower and much more sluggish than on r300g machine and
looks more colourful.
maybe it uses software rendering for openvg for some reason and this is how it
supposed to look ? i will provide a picture
2) no text in "text" demo and it says:
"EE r600_shader.c/tgsi_unsupported:868 - 25 tgsi opcode unsupported
EE r600_shader.c/r600_pipe_shader_create:339 - translation from TGSI failed !"

but this is probably not in your department and topic of another bug report
which should be filled.

anyway, i'm happy that openvg can actually draw something coherent on real
gallium drivers. maybe it will finally be a reason for those cairo guys to fix
their drm/kms & gallium & openvg & xcb "support", for 2D GUI/DE/vector graphic
editor people to utilize it and such.

slow lion from r770 with r600g and mesa-git right after r300g-opcode-patch.jpg

there is a memory leak :(
this demo, on both r300g and r600g, eats up memory very fast (and ~5 times
faster on r300g where it also rotates faster).
it also uses ~70-80% CPU time _on both_ machines.

hm. now then i look at it as two screenshots one-to-one and not two monitors
side-by-side, they look identical. must have been LCD differences :(
everything else stands though.

Since r300g doesn't leak any memory when used as an OpenGL driver, I guess it's
just st/vega that causes this.

I think r600g rotates the lion slower because it's slower than r300g. The speed
of the animation seems to depedent on framerate.

Since there isn't any other r300g-specific issue with st/vega, I am closing
this bug. Feel free to file a new one if you encounter any other issues. The
memory leak bug should probably be filed against Mesa core.
