After norton security suite update to 22.5 version on windows 10
Desktop screen keeps flickering, need help
Tried SF mode, SFWN nothing works
I had the same problem. but it wasn't because of Norton. The flickering problem occurred after installing Windows 10. I cured it by disabling Winows error reporting service. Not sure if your situation is the same, but you might try it.
Sorry for the inconvenience, We have released a fix tool to resolve Desktop screen flickering issue. Could you please follow the steps from the below Norton Support article on how to run the Fix Tool and let us know if this resolves the issue?
Norton Support Article: My desktop screen flickers after I upgrade my Norton product

From Norton’s response it sounds like NS might cause this problem and the following might not be applicable in your case, but for folks who recently upgraded to Windows 10 and they have Apple iCloud for PCs installed and use Photo Stream; I encountered flashing or erratic display behavior on mine and my wife’s computers shortly after upgrading from Windows 7 to Windows 10 Home (wife’s) and Professional (mine). My observation was that several running apps were failing during this erratic behavior and I had to perform the CTRL-ALT-DEL key sequence to access Task Manager and through a process of elimination (disabling apps) I found that disabling “iCloud Photos” in the Startup section of Task Manager stopped this erratic behavior and survived reboots. And, iCloud continued to function properly with Outlook sharing both Contacts and Calendars with our networked computers, my iPad and iPhone.
During this period of troubleshooting I didn’t uninstall or change iCloud in any way except to disable iCloud Photos from starting whenever our computers restarted. However, I discovered the root cause of this problem, at least for our computers, after discovering that I couldn’t save a picture attached to an E-mail to the Pictures folder or any of its sub folders on our computers. Turns out that when I clicked on the Pictures folder, right clicked and selected Properties, and then clicked on Security; the computer’s owner/administrator “UserName (Computer-Name\UserName)” was either not listed under the “group or users name” (on my wife’s computer) or was listed (on mine), but had no privileges. This issue also existed for all underlying folders, which included iCloud Photos. I discovered that by updating my wife’s computer to include her in the Security Section with Permissions set to Full Control and in my case to update my Permissions to Full Control; the correct Permissions updated at the Picture folder level and were then enumerated to all underlying folders and I could save new pictures to all folders.
I’ve now enabled “iCloud Photos” in the Startup section of Task Manager and the erratic behavior has not returned.
It appears that during the upgrade process security and permissions were somehow messed up because it all worked on Windows 7.
If others still have an issue, you might want to look at the security properties of the Pictures folder; which should influence all underlying folders. Interestingly, the Documents, Music, Videos, etc. folders were okay and didn’t exhibit this problem.
This might help some other Users who may have the same problem if they happen to find your post.
Yes, since it appears that NS can cause a similar symptom I thought, as a longshot, I'd post my findings regarding a similar problem. When this occurred on mine and my wife's systems; several apps, including NIS, showed as failing or not responding, so just in case NS or NIS wasn't the cause for other users I thought this might help in troubleshooting the issue. It appears to have helped quite a few people on the Apple iCloud for PC Community as well as Microsoft's Windows 10 Community.
I ran into this trying to remove Symantec.Cloud (yes REMOVING not UPGRADING) from a Win10 Pro 64bit machine. After it was removed, we rebooted and upon logging into the machine, the desktop was just violently flashing (under any profile) and the PC was pretty much unusable. we tried to create a new local acct but it wouldn't even log in, it was stuck at the normal Win10 stuff you see and after 30 min we hard booted it.
Was fine in safe mode - did a system restore back to before we removed Symantec - and it was NOT occuring
removed Symantec and again and this issue came RIGHT back.. So this is 100% a Symantec issue.. But luckily after a quick Google Search I found this link (below) which fixed the issue!!!
reboot the PC into safe mode and run the "Screen_Fix" from the link above
After running the Screen_Fix, I started to run the CleanWipe Tool - it said to reboot into normal mode to run the Tool, so I clicked yes and once the PC came back up in normal mode this issue was no longer occurring - I proceeded to run the Clean Wipe just to be sure Symantec was completely removed.
I'm glad you were able to fix your computer using the Screen Fix tool. Thanks for the feedback. This may help some users who have this problem.
