Well, look at simple_ra (the name is, clearly, misleading). It's quite ponderous. The sheet isn't anywhere near 5000 x 5000, though.
But others as well, like multimode (again, available through CGRAN), which has about half the block count of simple_ra.

I have a pretty full one on a 5000x5000 canvas running fine. Maybe Sebastian knows what might have changed in the GRC backend to cause this? Obviously it's not fake if multiple people are seeing it, but it's not affecting me at all. Tom Links: ------ [1] http://www.sbrac.org
