We noticed this issue as well when we upgraded from Citrix Receiver 4.4 to 4.7. Are you using folder redirection? For us, the issue only occured the first time the end user logged in after the upgrade and the Citrix Receiver icons were refreshed. It seems like Receiver is updating each icon one at a time and for each icon that gets updated it refreshes the explorer window so your desktop and start menu keep flashing.
For us, this was lasting for up to a couple of minutes, however we needed to deploy this update to resolve another issue so we just pushed it as is since it only happened the first time you logged in.
I wasn't able to recreate the issue on a user without folder redirection.
yes, same here. tested 4.7 & 8, same problem. I didn't say it as those are CRs, I wanted LTSR.
and you are right! it happens each time when receiver retrieve icons. I opened receiver verbose log, I can clearly see receiver re download icons time to time. so in my case, this flashing thing not only happens at start-off also during I am doing other things. which is quite annoying.
so I tried a couple of things, add HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Citrix\Dazzle\refresh 36000000( 10 hours), RemoveAppsOnLogoff RemoveAppsOnExit as False... all didn't help.... the case is still on going with citrix tech.
