Hi there,
it looks like sv_pure (2) blocks textures on several maps. I played dod_argentan twice today and recognized that the wooden ground texture and some others, too were missing. After playing dod_salerno (custom map) twice, it's radar background disappeared. Strange.
Here is a screenshot of it:

I think this bug is clientside (Windows) because the bug seems to disappear after restarting the client and rejoining the server.
