Tiling: white lines and cache

[Yves Bolognini]

Hi list,

Two questions about tiling. Does anyone know something about that?

I'm using tiling for a raster layer and I get a 1-pixel width white
lines between some tiles. Vector layers based tiles are OK.

If I don't wait enough between each pan during first navigation (tiles
cache empty), some tiles are not drawn. Then it's impossible to get
those tiles without emptying the cache.

Thanks in advance,
Yves
