You have not supplied the command line you are using, which makes it pretty
much impossible to reproduce your problem. I have tried a variety of likely
configurations, all render entirely correctly as far as I can tell on the 9.22
release binaries.

I suspect that this was caused by the new scan converter and was fixed in
commits:

http://git.ghostscript.com/?p=ghostpdl.git;a=commit;h=d9f068ae6d612f09dd37915edd56381c6a9167b7

or

http://git.ghostscript.com/?p=ghostpdl.git;a=commit;h=684f73e8deefacb2aa5d2277f3154b68809b2ab7

or

http://git.ghostscript.com/?p=ghostpdl.git;a=commit;h=1626f36c9b6ae68abad7818be7cfb2a95f4ecffe

However, since I cannot reproduce the problem in the original released
binaries, I cannot tell for certain.

Actually, I used the Ghostgum GSview 5.0 GUI interface to invoke Ghostscript
9.22 to render the PS file.

GSview options are:

Safer (on)
Auto Redisplay (on)
Unit (pt)
PStoText (normal)

Its always important to tell us how Ghostscript is being used. I confirm that
the 9.22 release binaries exhibit a problem, the current code does not. Almost
certainly fixed with one of the commits described in comment #1.
