Windows 10: Search bar flickers/disappears

I’m on 1909, up to date with windows updates. Occasionally when I click the search bar in task bar, it’ll flicker, freeze, turn black, then pop back up 30 seconds later. Event viewer is showing that Searchui.exe crashed and the faulting module is dcomp.dll. It’s not system breaking but it’s a bit of an annoyance. Anything I can do to fix this?

Search Bar/Cortana

Hello,

Thank you for posting your concern here in Microsoft Community and welcome to the Windows 10 family.

From the description, I understand that you are still receiving the pop up notifications, despite having disabled the search functionality in windows 10.

Steps to disable the Search Bar

• Right click on the task bar.
• Select the "Search" option.
• Select "Disable."

However, if the above steps don't work out, perform the below suggested steps and check if it helps to resolve the issue.

Open a CMD window started as Administrator.

Repair corruption: Dism /online /cleanup-image /restorehealth.

Run this command next: Sfc /scannow

Now run these two commands:

PowerShell -ExecutionPolicy Unrestricted

Get-AppXPackage -AllUsers |Where-Object {$_.InstallLocation -like "*SystemApps*"} | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

Hope the above information was helpful.

Thank You.

 

Scroll bars

I am having problems with lists that have scroll bars. Best example is the navigation pane of File Explorer. If a vertical scroll bar is present the navigation panel will jitter (flicker)! If I expand file explorer vertically so that the scroll bar disappears
the jitter will stop. Another good example is the list of Apps and features - my list is large and so the window cannot be vertically expanded so that the scroll bar disappears. This happens also in several of my apps. And, it also happens in my browser
searches. The jitter is so severe that I cannot highlight an entry to modify it. Any help?

 

Desktop items open Libreoffice; windows bugged and flickering

My mother's PC had the most bizarre bug I've ever seen this morning.

PC specs: Windows 10 Home 64bit
Version: 1903 when problem occurred (1909 now)

What happened:

• all desktop items, including folders, opened in Libreoffice Writer; once open it displayed a blank document then began flickering as if it had bugged while scrolling
• opened Task Manager from the task bar, selecting the second tab opened the final tab, which began flickering like Libreoffice
• problems stopped after a restart, then occurred again after another restart; then stopped after the PC ran for a short time
• no error popups or BSODs
• she said Candycrush reported an error earlier but it didn't occur when I looked at it; she said it mentioned "something about the desktop"

Steps I've taken:

• did a quick virus scan then reboot scan with Windows Defender; no problems found
• sfc /scannow; no problems found
• installed update KB4537572 and upgraded system to 1909; updates appear to have been successful, no other updates available

At the moment the problem has disappeared, but since it reoccurred previously I'm not sure it hasn't been fixed.

I'm out of ideas. What else can I check and what other tests can I run? Based on the given information could anyone suggest what the problem might be?
