Incomplete tiles returned

[zstatmanweil]

I am working with 10m resolution data without overviews. I don't need data returned super fast, but I potentially want to look at it at a few different zooms. I have no issue looking at the data at zooms 14/15/16, which makes sense as it is close to the native resolution of the data. However, when I try to load tiles at a lower zoom, say 11, I get these incomplete tiles returned:

I have tried to up the time_limit and max_size and that doesn't seem to change what is returned. Is it possible to return data at a lower zoom without overviews if you have the time and patience? Any parameters I can set to ensure the whole tile is returned?

Thanks!
