Thank you for reporting this. It was due to a leak of the sg_attachments structure in the render target.

Need to reopen this issue as it still occurs, though only after six or seven Load->Exit iterations.

This may be the fault of the unfreed world in the game. Before, all render targets ever created would be leaked. Now only those that are saved somewhere. I will reopen this for now.

[marekmaskarinec]

It was exactly as I said. I fixed this issue in the game by not storing the render targets anywhere in the world structure. However, I think Tophat should check if it's possible to create a render target and return an error.

Reading this again, this is an error about samplers, not passes. This is caused by a large number of images. But I think this too caused by the unfreed world struct.

[vtereshkov]

Not a problem anymore.
