Bug ID: 37398
           Summary: Urban Assault black screen when using software
                    renderer and DDSCAPS_SYSTEMMEMORY

Workaround

Once Bug #37307 is resolved then Urban Assault runs into another issue (at
least, when using the software renderer).  The game has a black screen and just
hangs there, apparently due to an unexpected DDSCAPS_SYSTEMMEMORY capability
being set.  Workaround attached.

Note: This commit is later moved (commit
9443c95a895a530fdbbb607758f674467e2010c7), but the issue persists.
