3.1 - Tiles bug?

I tried out the tilesets with 3.1, to see what they look like. I noticed that when using David Gervais tiles, the unexplored 'void' of the dungeon gets filled with the 'cloak' icon (brown cape-like shape). This does not happen with other tilesets, that correctly display empty blackness.

What OS and version are you using?

Same bug occured with an earlier version of Angband, 2.9 or so, I think.

Ah. One of my favourite bugs. This occurs because the Windows port (and perhaps the underlying Angband code IIRC) makes the assumption that graphics tile (0,0) is the blank tile in various parts of the code. However the Gervais 32x32 tile set violates this assumption.

Historically this manifested itself as transparent graphics tiles ended up having the cloak as the background.

I just fixed it by moving the cloak to a new position, and setting the (0,0) tile to the background. I was never able to convince Robert Ruehlmann of the necessity of doing this...

Does this mean I could just steal the UnAngband 32x32 tiles to avoid doing the work myself?

While I've replicated this in 3.1.0beta on Crossover, I've taken a look at 32x32.bmp and the top-left tile is still black. Even weirder - it looks like 3.0.9b uses the exact same bitmap, and that doesn't exhibit the issue...

Is it a possibility that the tile masks for PNG graphics included the original cloak mask on the blank tile?

My thought is that there was a fix made for the fact that the darkness was not at position one. Then the darkness was moved to position one and there was something in 3.09 that accounted for this. Then 3.1 came out with the original fix but not whatever they had in 3.09 so maybe the fix is fixing a problem that is not there and unfixes it
