Hi Arthur,
Not sure what you mean by “snipped”, but I would recommend using Chimera’s menu: “File… Save Image” or command “copy” rather than some screenshot or screen grab method on your computer.  Then, things to try are:

(1) decreasing the supersampling level.  Default is 3x3.  You could try 2x2 and if that didn’t help, 1x1 (no supersampling).  This is most likely the problem.  

(2) using a different file format, say PNG instead of JPEG.

I hope this helps,
