Description phil 2002-06-27 18:03:01 UTC
Description of Problem:
gv runs quite slowly under Redhat 7.3, displaying text
a line at a time.  It was much faster under 7.2 and prior.

Version-Release number of selected component (if applicable):
gv 3.5.8
GNU Ghostscript 6.52 (2001-10-20)

How Reproducible:
Always.

Steps to Reproduce:
1.  use gv to view the attached postscript file.  (p1.ps).
2.  compare the result with using gv p1.ps on Redhat 7.2 and prior. 
 
Actual Results:
gv displays the text very slowly.

Expected Results:
gv displays much faster under Redhat 7.2 and prior.

Additional Information:
I found that if i did 'gv -noantialias p1.ps', it displays much faster.
However, it doesn't look as good.
So something in the antialiasing appears to be making it run slowly.
The probelm appears to be in gv. gs p1.ps runs quickly.

The attached sample p1.ps is the first page from a technical report here.

Thanks for your help.

This seems to have been caused by a change in the file:
/usr/X11R6/lib/X11/app-defaults/GV

Find the line which reads:
GV.gsX11AlphaDevice: -dNOPLATFONTS -sDEVICE=x11 -dTextAlphaBits=4 -
dGraphicsAlphaBits=4

and change it to:
GV.gsX11AlphaDevice: -dNOPLATFONTS -sDEVICE=x11alpha

This changes things back to how they were under 7.2 and makes gv fast again.

Yes, this is fixed in the beta gv.
