Plot lines drawn incorrectly with X11

I am making plots with ROOT over ssh X11 window forwarding. When I do this from a Mac, the plots display correctly. When I do this from Linux, however, the lines do not fully. Instead they show up randomly dotted (see attached picture). Also, the data point dots don’t appear, just the error bars. On a Mac, the red blue and cyan lines are solid and the data dots appear. I can’t find any instances of this problem in the forum and I hope this is the correct place to post.

My question is: am I missing some dependency? How can I solve this problem?

I have tried:

  1. Updating xorg [edit: this update didn’t take effect until I restarted]
  2. Changing screen resolution

Here’s my solution to the above problem. There may be a bug in X.Org X Server version 1.18.4. By updating to version 1.19.1 and restarting the window manager, this problem was resolved. You can check the version of Xorg via the command “Xorg -version”.
