Fretsonfire text corruption

When I start fretsonfire there is a visual glitch around the text in the main

game patch

The game tries to create the texture of maximum size for the glyph cache. I
think it's not a good idea. It doesn't even start on my evergreen due to this.
You might want to try attached patch for the game (for the "src/Font.py" in the
game folder), it should fix this issue.

Though, it seems the driver doesn't handle this situation correctly too. I'll
look into it.

Probably the driver can't do anything other than report the "out of memory"
error (error code -12 in your dmesg log). The game just shouldn't use such huge
textures, it shouldn't use MAX_TEXTURE_SIZE as the size for texture (this
result in 0.4 GB on r6xx/r7xx, 1.4 GB on evergreen, next step will be >5 GB
with future GPUs). I think it makes sense to tell the game developers about
this issue. With my patch it uses 1024x1024 texture (~5 MB) and runs fine
without artifacts or error messages in the logs (though I haven't tested it
much). I don't know exact requirements for this, the game developers should
know what size is really required.

the patch worked for me :)

But it's strange that fretsonfire work without problems with catalyst... maybe
they set MAX_TEXTURE_SIZE to a different value.

I think the value of MAX_TEXTURE_SIZE is the same with catalyst, but probably
it's using compression or some other tricks to reduce the size of the texture.

This explains it. Closing.
