06/29/2020, 10:54 PMhttps://www.carlstalhood.com/category/workspace-app/ Scroll about half way down - We had some issues such as this with the old reciever on some horrendously outdated unpatched W7 machines, found Carl's site very useful to help with the refreshing issue at the time.

06/29/2020, 11:52 PMIssue started with Receiver 4.0 line IIRC. Reciever 3.X does PNA correctly. Receiver 4.0 the flickering is because it grabs the PNG from Storefront for each icon, makes a .ico file for each, assigns it to the shortcut then refreshes your desktop to make the icon appear. But it doesn't batch (at least with 4.12 -- the last version I used at my last org) so each friggin step is synchronous. Flicker, flicker flicker flicker
Trentent
06/29/2020, 11:52 PMThe solution we used? We ditched PNA and use the "Store" interface. No more flickering, no more unusable desktops for 5 mins while 200 apps loaded

06/30/2020, 12:15 AMThanks Trent but unfortunately I don't use pna in this setup.
Ray Davis
06/30/2020, 12:53 AMBut the same process seems like its happening. Flicker ICON, Flick ICON, so on and so on.
t
Trentent
06/30/2020, 1:46 AMinteresting. Maybe some configuration for PNA is turned on making it do the process, even if it doesn't create a PNA structure?
Trentent
06/30/2020, 1:47 AMThe logging for Workspace/Receiver might help. The logs can be super verbose
Trentent
06/30/2020, 1:48 AMIIRC, we found the various policies by this process: Exit reciever/workspace, delete Citrix Workspace/Reciever policy keys, start reciever and connect and launch resource
Trentent
06/30/2020, 1:48 AMNo issue? --> Exit Receiver, Apply Policy, remove key/value, etc...
Trentent
06/30/2020, 1:48 AMcontinue until group of settings is found
Trentent
06/30/2020, 1:49 AMI believe Citrix defaults to the Store/Service so this should validate that I think
r
Ray Davis
06/30/2020, 2:03 AMWell Xenapp Services support is enabled in the store, Which I don use it, another old setting that was ticked before me .So I will go down that path. Thanks Trent.

06/30/2020, 4:25 PMIf we have PNA enabled, how do I tell if we're using it? I don't think we are, yet we have the same flickering icon problem - but ONLY if we launch a published app within our published desktop (to another machine)

Ray Davis
06/30/2020, 5:37 PMIn store front you will see this.
Ray Davis
06/30/2020, 5:37 PMThen you will see it in StoreFront under XenApp Service Support on the right hand side.
t
Tim Riegler
06/30/2020, 9:03 PMThat's if it's enabled, right? How can I tell if clients are configured to use it?
Trentent
06/30/2020, 10:23 PMI with I documented, but these log files might lead you to how to check
Trentent
06/30/2020, 10:23 PMThis is with PNA mode enabled
r
Ray Davis
06/30/2020, 10:25 PMI thought you had to specify the path to the PnA in workspace to use it. Pnagent.xml or something like that.
Ray Davis
06/30/2020, 10:28 PMMeaning you would see this In the workspace path.
https://\<StoreFrontFQDN\>/Citrix/\<StoreName/PNAgent
Ray Davis
06/30/2020, 10:30 PMI also thought that the pnagent was only for legacy Verison of recover. I didn't think workspace can use that.
t
Trentent
06/30/2020, 10:31 PMIt can. Same features exist. Essentially, "PNA" mode is putting icons on the desktop. Last I checked workspace allowed that
Trentent
06/30/2020, 10:32 PMFound a screenshot of previous org's "PNA" mode:
Trentent
06/30/2020, 10:32 PMput shortcuts on desktop/startment, etc
Trentent
06/30/2020, 10:32 PMflicker flicker flicker
r
Ray Davis
06/30/2020, 10:34 PMDazzle is Pnagent? Ok I'm lost because I don't have set on a store and I'm still getting icons,,, self-service mode and shortcut placement
Ray Davis
06/30/2020, 10:36 PMI found this on Carl's Stalhood site.
"The PNAgent module is not included in Workspace app or Receiver 4.0 and newer. The older Receiver Enterprise includes the PNAgent module, but does not include Self-Service. The last version of Receiver Enterprise is 3.4."

Trentent
06/30/2020, 10:37 PMMy bad for using older terminology. PNA == Icons on the desktop/startment
r
Ray Davis
06/30/2020, 10:37 PMI see now. Haha you had my mind like WTF and I losing it lol
Ray Davis
06/30/2020, 10:38 PMI see now. So it's using the like placement and the flicker flicker bs.
t
Trentent
06/30/2020, 10:38 PM🙂 Git rid of icons on the desktop/start menu and you'll get rid of the flicker and slownes
r
Ray Davis
06/30/2020, 10:39 PMOh man, that's hard to do. Dang well let's see what I can do
t
Trentent
06/30/2020, 10:39 PMFor each icon generated Citrix will "refresh" the desktop. The refresh is not instant, takes time. The more apps, the more icons, the more flicker
Trentent
06/30/2020, 10:42 PMit sucked for us too. We switched to self-service mode because of these problems. Our users stuck with 3.4 for as long as possible until the SHA1 issue made it impossible and we had to migrate to 4. Self-Service without icons on desktop... But we did change it so some critical, mandatory, icons were on the desktop
Trentent
06/30/2020, 10:42 PMIIRC, we used GPP to put a short cut to "MyApps" on the desktop, which just opened the self-service store. Seemed to get acceptance from the users OK
