IDL produced graphics.

Description of problem:

With 9.05 (-1 and -3) on F17 we see character artifacts in the attached image.  We don't see these with 9.04, including 9.04-9 built on F17.  The image is produce with IDL with something of a kludge of setting the fontsize to a very small number (.001) to suppress axis labels.

Version-Release number of selected component (if applicable):

This is the expected rendering (9.04 and earlier)

Bad rendering

Bad rendering with 9.05
Comment 3 Orion Poplawski 2012-07-16 13:03:02 EDT
I tried reproducing with upstream's binaries, but ran into other problems (segfault with 9.04 and no X display with 9.05).  Filed that upstream, see linked bug id.
Comment 4 Orion Poplawski 2012-07-16 16:31:28 EDT
Apparently this is an issue with the x11alpha driver.  Image appears fine with -sDEVICE=x11.  This was first noticed with gv which uses x11alpha to render.
Comment 5 Orion Poplawski 2012-08-02 17:43:45 EDT
Upstream reports that this is now fixed in git and that a new release should be forthcoming in a week or two.
Comment 6 Orion Poplawski 2012-10-08 19:03:26 EDT
Any chance we can get 9.06 in F17 to fix this?  Or backport the fix?
Comment 7 Tim Waugh 2012-10-09 05:52:36 EDT
It isn't even in F18 yet.  Let me get it in there first, and then we look at getting it into F17.
