Current behaviour for parts of the isometric view in which there is no sprite is glitchy. Redrawn objects simply overlay the gap leading to artefacts and lingering objects (Glitches_SpriteGap_Gl1.png).

I suggest that prior to redrawing sprites the region is filled with a neutral colour (such as black or a mid grey). This would eliminate redrawing artefacts and make drawing of sprites 100% deterministic/predictable (mocked up in Glitches_SpriteGap_Sugg.png).

This would be particularly useful for 32bpp graphics where making ground tiles with anti-aliased edges which tile perfectly (to prevent redrawing glitches or sprite draw order problems around the tile edges) is essentially impossible.
