VisualWorks: Pixmap errors thru Citirx

[Charles A. Monteiro]

Hi, we been getting graphics primitive display issues , that only
occur with certain users (2) and are intermittent. Furthermore, note
that all of the users go through Citrix. They are running VW 7.5, both
users are on a multiple monitor setup. If it was a presentation server
issue i.e. Citrix server you would think you would see this manifested
all over the place but we don't. So it would seem that there might be
some interaction between the Citrix client piece and the local PC.

BTW, these errors occur under different circumstances i.e. there is
code "cause" of this per se.

I've been ask to get feedback to better understand this, and to come
up with some solution both short term and long term.

1. Anybody have experience running VW under Citrix and have
encountered these issues ?
2. Can anybody think of a workaround e.g. we of course could trap for
them and ignore but hmmm ... ?
3. Is software the answer or can this also be a hardware thing that is
aggravated by the use of Citrix ? i.e. is the longterm a matter of
beefing up the local resources or is this not a resource issue ?
4. In the case of Citirx there is no way that the network
circumstances could cause this type of error ? don't think so

Again, brainstorming , all feedback appreciated.

thanks

I haven't heard of such a problem. It would probably be helpful to
know what the characteristics of the problem operation are. e.g. one
thing that might happen is that it tries to draw with a zero or
negative extent and fails the primitive. Probably also helpful to
contact support.

its just standard gui re-display, no custom graphics ops, but its thru
Citrix. thanks
