The source code is:
.ps 12 .vs 14 .nf .EQ p ~ = ~ q times sqrt { ( 1 + ~ (x / (q * q) ) } .ENThe output on Windows with Acrobat had a long tail to the square root sign over the top of the whole expression.
Okular has just a simple square root sign on the left of the expression, i.e. no encompassing tail over the top.
evince has a box with segments over the entire expression to the right hand side of the square root sign.
Evince used to work flawlessly with groff 1.22.3 on Centos 6.6. Stay safe - Damian Pacific Engineering Systems International, 277-279 Broadway, Glebe NSW 2037 Ph:+61-2-8571-0847 ..
