Description Fabio Pedretti 2011-10-21 06:56:55 UTC

Monsters in sauerbraten have missing textures. I bisected and got:

There are only 'skip'ped commits left to test.
The first bad commit could be any of:
163629fd05166b78d70c2c26f4a922b296e8999d
0dc97e7fd49a5b8db25b95a1020fc598dba5cf65
We cannot bisect more!

the first introduce an all screen corruption, the second change it to missing textures in monsters.

My chip:

Yes (tested on current git and also with 0dc97e7fd49a5b8db25b95a1020fc598dba5cf65 reverted: both type of corruptions are fixed with the patch).
