Hello,

With a debugging FIXME and filtering the caps one by one the dwCaps that causes
trouble to the gdi/no3d renderer is identified as DDCAPS_ALIGNSIZESRC.

With this debugging patch the application fails:

--- diff ---
+    FIXME("caps.ddsOldCaps.dwCaps was %#x.\n", caps.ddsOldCaps.dwCaps);
     caps.ddsOldCaps.dwCaps = caps.ddsCaps.dwCaps;
+    FIXME("caps.ddsOldCaps.dwCaps wants %#x.\n", caps.ddsOldCaps.dwCaps);
+    caps.ddsOldCaps.dwCaps &= ~DDCAPS_PALETTE;
+    caps.ddsOldCaps.dwCaps &= ~DDCAPS_OVERLAY;
+    caps.ddsOldCaps.dwCaps &= ~DDCAPS_BLTSTRETCH;
+    caps.ddsOldCaps.dwCaps &= ~DDCAPS_BLTFOURCC;
+    caps.ddsOldCaps.dwCaps &= ~DDCAPS_BLT;
+    caps.ddsOldCaps.dwCaps &= ~DDCAPS_ALIGNSTRIDE;

+    caps.ddsOldCaps.dwCaps &= ~DDCAPS_ALIGNBOUNDARYDEST;
+    FIXME("caps.ddsOldCaps.dwCaps got %#x.\n", caps.ddsOldCaps.dwCaps);
