Could you make a try it with 256 px also?

Looks good without changing generator settings:

I am only looking at the pattern from a technical point of view here, quarry rendering in general has so many issues now i would not really know where to start.

The suggested pattern is horizontally closed packed rather than vertically as it was before and has a larger aspect ratio mismatch - the latter however is due to an error in jsdotpattern which is now fixed and you can get a much less distorted triangle pattern with that now:

http://www.imagico.de/map/jsdotpattern.php#x,256,jdp2599;gt,45,32,32;rd,1,0,0,quarry1,1,7,6,0,jdp59560,e6e6e6,c5c3c3;

http://www.imagico.de/map/jsdotpattern.php#x,256,jdp76470;gv,45,32,32;rd,1,0,0,quarry1,1,7,6,0,jdp27974,e6e6e6,c5c3c3;

There are other options with neither the horizontal nor vertical direction accentuated but they won't work at this pattern size and density:

I personally see no problem here, but new proposition looks also good for me, so I can just use it if you want (first pattern generated and sanitized with newest jsdotpattern):
