Managed to duplicate this behaviour. It happens when the surface is exact the same or one less than the max texture size. Will look into this.

I see some code added for this, could you please check if this bug still applies?

Note to self: Make sure sprite packer dont pack single frames. Also textures at edges dont need extra width.

Could you add the offending sprite to the resources in the sprite Test in clanlib?

I'll look into it next week. It should first of all use the max-texture-size from OpenGL, and not a fixed 1024 :)

The SpritePacker gets stuck in an endless loop in Advent at line sprite_packer.cpp:125, backtrace follows below. This might be because Advent uses very large sprites, larger than what the gfx card can support (2048x600 or something like that)
