It is a bug in the X11 server, not in GrADS. Your graphic will look normal if you draw it in batch mode and use gxprint.
<div><br>
</div>
<div>These are the old tickets that resolved the issue right before GrADS 2.1 was released:
<div>
<div> <a href="https://github.com/XQuartz/xquartz-old-tickets/blob/master/ticket/525.md">https://github.com/XQuartz/xquartz-old-tickets/blob/master/ticket/525.md</a></div>
<div>
<div> <a href="https://github.com/XQuartz/xquartz-old-tickets/blob/master/ticket/768.md">https://github.com/XQuartz/xquartz-old-tickets/blob/master/ticket/768.md</a></div>
<div></div>
</div>
<div><br>
</div>
<div>But it seems that for some users it is still a problem, especially if you are using linux as your desktop OS. I have heard it is also a problem with RedHat7, but I can’t reproduce this bug on any of the systems to which I have access, so there is not much
I can do. Graphics render perfectly for me using XQuartz on Apple OSX and/or ssh’ing to Redhat/CentOS 5 and 6. </div>

I'll contact COLA again. For us is quite annoying because 2.0.2 can not<br>
open files form our THREDDS server (2.1.0 does).<br>

we also have the same problem when running any version of GRADS with<br>
Cairo on a LINUX machine.<br>
<br>
We communicated COLA on the issue, but they don't believe that it is<br>
GRADS-related problem because it doesn't show up if GRADS is run via<br>
X-ming from windows machines.<br>
<br>
The 2.0.2 is the last version that runs OK on LINUX machines.<br>
Unfortunately, switching back to the 2.0.2 is the only solution here at UMD.<br>

Hello<br>
<br>
I'm having issues with grads-2.1.0-bin-CentOS5.11-x86_64.tar.gz<br>
binaries when plotting data. Using GrADS tutorial<br>
(<a href="ftp://cola.gmu.edu/grads/example.tar.gz">ftp://cola.gmu.edu/grads/example.tar.gz</a>) example, I'm getting this<br>
ugly picture in three different systems (Debian GNU/Linux 8,openSUSE<br>
13.2 and SLES 11 SP3).<br>
<br>
Using grads-2.0.2-bin-CentOS5.8-x86_64.tar.gz, in all those systems<br>
everything goes fine.<br>
<br>
Did someone got this issue?<br>
<br>
Thank you,<br>
<br>
