Hi All
I have a problem that is annoying me a little and hope someone has come across it.
My enironment is PS4.0 on Win2k3
We are trying to access an external suppliers Web Interface page.
If a user copies the address and launches it straight from the browser on the client workstation, the page is displayed and graphics all look fine.
When I publish this same page (as a published app), via citrix using the server's IE, the resolution seems to drop slightly, and I can see the images show up at a lower resolution slightly.
I have published the app at different screen resolutions eg 800x600 and at different colours from 16 colours to 24 bit and has made no difference.
I also have enabled speedscreen acceleration (via the Citrix policies) but with setting 'do not use lossy compression' and this has done nothing. I then disabled speedscreen acceleration altogether but still the same problem with loss of quality.
From the 'problem' servers console, I manually launch the website (so bypassing RDP or ICA connection) the website launches with the detail and clarity I am after. But if I launch the published application from the same server, I will notice the loss in quality of the website.
Help anyone?
Try and publish this web page as content, instead of an application when creating the published application.
Hi Robert, thanks for your response. Unfortunately the app has to run on the citrix server, as there is a special printer utilty that is installed only on this server, which imports the printer connected to that server. If I publish it as a published content then when the user prints, it goes to their local printer, which we dont want.
Are all of your servers configured to use farm settings for speedscreen and ICA display settings, or do you have each server configured individually?
However they are configured, in the ICA display settings what is configured for Max memory for each sessions graphics? If this is too low it can degrade image quality.
Do you have any CAG's or any other device that could be causing compression in the ICA session?
Hi Robert
SpeedScreen Browser acceleration is not enabled farm wide, and also have not enabled it on the specific server.
ICA setting (farmwide) the following is enabled:
Discard redundent graphics operationsAlternate caching method (5625 kb)Degrade resolution firstNotify users of session degradation
I don't have a CAG which could compress the ICA session. I am getting this problem just conecting to the server from internal LAN, either via ICA or RDP sessions.
When you connect to the Web Interface check the properties of the session and Window Colour before connecting

Hi EmilBeck
Thanks for your suggestion, I check my published app and the remote sites published app's properties,
my published app is:
DesiredColor=8DesiredHRES=800DesiredVRES=600
remote published app is:
DesiredColor=8DesiredHRES=640DesiredVRES=480
although I did notice an extra 2 lines in the remote app :
Compress=onMaximumCompress=on
This part needs to be investigated.
Turned off compression, no difference
Funny though, I built a server from scratch and tested launching of the WI at each stage.
Win2K3 server with Citrix client - RDP to server, load IE, WI looks fine
Installed Terminal Server and no other updates- RDP to server, load IE, WI looks fine
Installed Citrix PS4 with no other updates - RDP to server, load IE, WI does not look fine.
So by installing Citrix, something is screwed.
Try publishing a Desktop with 16bit colour, then connect via PN and WI, right click the desktop and check the colour quality - still 16bit? Then try the website.
OK I think I have found the solution.
It seems like it might be client related and Seamless related.
OK. For those who choose to run the app in seamless mode, but fix the screen rendering issue, the following Citrix Article is the one to follow: CTX204071
I have reversed what I did in previous post and applied this registry edit in the article.
