screenshot of breakage due to regression

http://cgit.freedesktop.org/mesa/mesa/commit/?id=603741a86df0e43c0b52e8c202a35c7fe2fc1d9c does break displaying the wesnoth-gl branch when using the r600 classic driver. Things are displayed nicely using r600 gallium. It looks like some completely wrong textures are displayed (so the "wrong stuff" displayed appears to be something from a wrong region of the grahpics ram or something like this). Wesnoth is using FBOs (regarding what I heard from alink) to display stuff.

I attached a screenshot of what is shown as well as what should be shown.

To reproduce this:
svn co -r47099 svn://svn.gna.org/svn/wesnoth/branches/ogl wesnoth-ogl
cd wesnoth-ogl
cmake .
make
./wesnoth .

I explicitly mention a revision in case that all the menu setup stuff is changed over the next days. In general compiling wesnoth can also be done using scons or autotool and always does require the dependencies listed at http://wiki.wesnoth.org/CompilingWesnoth . The resulting svn checkout needs about 1GB on the harddrive and compiling will take some time (usually longer than compiling a kernel).

Does it works now ?

Comment 3 Nils Kneuper 2011-02-13 08:27:22 UTC

Yeah, it seems to be fixed now, though I was probably using a different card when last testing it. Now using evergreen (hd5850) and it does display things correctly, both when using r600c as well as r600g.
