its gridlines that is the problem. its calling rendering.clear() instead of rendering.clear('factorio-gridlines'). Most of the code for this mode is "inspired" from by the chunkychunks mod. The clean function it borrowed from chunkychunks calls rendering.clear('ChunkyChunks') which is what you want to do, but in gridlines the argument to rendering.clear is missing add blows away all rendering done my mods instead of just the ones created by gridlines.
I tried contacting the mod author about this issue but he has not responded for over two weeks, so no idea if this will ever get fixed without a fork.
Note this breaks rendering on a lot of other modes as well...
