We're experiencing intermittent font display issues in some of our
applications since updating to SRSS 4.2. The symptoms are that
fonts are sometimes displayed incorrectly with some letters being
abnormally large, some abnormally small, and some letters having
the wrong characteristics (e.g. italic). Capital letters and numbers
seem to be affected more often than lower case letters.
We believe that this may be a Sunray display issue (rather than
an application or X server issue) because:
- screen captures of the affected windows don't show the
problem, although I did manage to get an image showing
the issue using a camera
- forcing a redraw of the affected screen areas, or
restarting the Sunray session via STOP-A often resolves
the issue for a given window
Our setup is:
- SunFire V445 (sparc)
- Solaris 10 U8
- SRSS 4.2 (with latest patch 140993-01) running the Xnewt X server
- CDE window manager
- Sunray 2 client with firmware GUI4.2_140993_01_2010.01.21.17.35
- older apps (one custom C++, one using Oracle Reports)
We did not experience this previously using SRSS 3.1 or 4.1, although
we were using Xsun with 4.1.
I found the following 2006 posts which seem to describe exactly
the same problem with SRSS 3.1 on Linux:

I'm going to try the suggested workaround (touch
/etc/opt/SUNWut/ut_disable_glyphcache and restart SRSS) but
that will have to wait until I can get a maintenance window.
My questions:
- Is anyone else seeing this on SRSS 4.2?
- Will the work around impact performance for our remote
users?
- Any idea if this is a known issue? We have support and
I've searched Sunsolve without success, but I'm concerned
that my search didn't turn up CR#6469850 mentioned in one
of the links above.
I'm going to file a support request with Sun on this, but I'd
like to do this armed with as much infomation as possible.
Thanks,
Sean Walmsley
