--- Comment #9 from Matteo Modesti mattemod@gmail.com 2008-05-07 22:58:39 --- I tried both Wine 0.9.61 and 0.9.58 with older fglrx versions (from 8.471.3 down to 8.40.4) but nothing changed...
However, i noticed that with older fglrx versions this line fixme:d3d:test_pbo_functionality >>>>>>>>>>>>>>>>> GL_INVALID_OPERATION (0x502) from Loading the PBO test texture @ directx.c / 3518 doesn't appear, i don't know if it can be useful...
Finally i returned to fglrx 8.476... but then remembered that (like i said in this bug's Description) radeonhd driver doesn't support direct rendering yet (and i could start Morrowind using it). So i tried to add this line Option "NoDRI" "Yes" to my xorg.conf's Device section, then restarted X and tried to launch Morrowind: it works!! Painfully slowly but it works! So i think it could be a DRI related problem... so now the bug-hunting sphere is a bit reduced i think (and hope) :)
I'm going to attach my glxinfo output with and without "NoDRI" option enabled to the next comment.
If you need any other info or someone for testing patches or anything else, please ask, i'd like to see this bug cut to pieces :P
