Windows 10: Microsoft’s new fix for Chromium’s scrolling & CPU usage on Windows

Microsoft has been actively contributing to the open-source Chromium that has replaced EdgeHTML in Microsoft Edge. Microsoft plans to bring a lot of new capabilities and improvements to the open-source platform, and it will benefit all Chromium browsers including Chrome.

Microsoft is also porting Edge-style smooth scrolling to Chromium and the company has now proposed a new series of changes to further enhance the experience.

As a two-year-old bug post on Chromium noted, Chrome’s performance takes a hit when scrolling on certain webpages with a large number of elements set to the sticky or fixed position.

In theory, position: sticky allows an element to keep showing on the screen throughout scrolling. For example, titles of webpages or text in the menu that remain placed on the top of the screen when you scroll.

A Chromium developer notes that tests revealed 13% CPU hikes on Windows and CPU increases more than 100% upon scrolling with trackpad and mouse wheel respectively.

The bug has been ignored for more than two years, but an engineer from Microsoft Edge team has figured out a solution and observed the following improvements:

• Significant improvements in Blink.MainFrame.UpdateTime (~50%) around compositing lifecycle updating.
• Significantly more main-thread frames were produced on my dev machine (857 to 1375).
• Smoothness metric increased from 87% to 94%

Windows Performance Analyzer revealed ~22% main thread CPU-time improvement. “This was for a manual scenario where I held down the ‘down arrow’ key for ~60 seconds after page load,” wrote Sam Fortiner, Principle Software Engineer at Microsoft.

A commit with the following details has been marked active:

Enter assumed-overlap mode after encountering a fixed or sticky element. This speeds up composited scrolling, because it no longer has to re-do the overlap test on every frame.

New look of radio and checkbox


On Windows 10, Microsoft is also implementing a new look for radio and checkbox on a webpage. According to a commit, this change will allow the radio and checkbox to use Windows 10’s accent color.



“This CL implements the new look of radio (accent color), checkbox (accent color and indeterminate state), range (accent color),” a commit reads.

Windows Explorer high CPU Usage in Windows 10

Hi Andrew,

Usually, too many background processes can boost your CPU usage. Since you already disabled the apps that are not necessary on startup,
we suggest checking the applications running once you have successfully boot Windows 10. To do this, simply follow the steps below:

• Click on the Start button and type Task Manager on the search box.
• On the Task Manager window, you should see the programs running.
• Click on the More details drop-down button to see the total number of apps running and their real-time CPU usage.

From there, you should see what applications are running on high CPU usage. You can also
restart the Windows Management Instrumentation service and see if your CPU performance will improve. Follow the instructions below to restart the service:

• Click on the Start button and type Services.
• Scroll down the list and look for Windows Management Instrumentation.
• Right click on it and select Restart.

Should you have further questions, please let us know.

Windows 10 High CPU usage Fix

Hi i'm writing here to post an answer to the Windows 10 High CPU issue that i found and also ask the Microsoft Team why does this occur so i can understand it.

So to the answer; my CPU usage all of the sudden became high over the last few weeks, i'd tried to trouble shoot as others and Microsoft had suggested, though nothing worked. Microsoft has suggested to create a new account and transfer files which also proved
fruitless after transferring files as explorer.exe again consumed high CPU usage. It was just luck that i stumbled across the solution in one of these threads that linked to an answer from 2011.

Firstly i just want to state that i did download process explorer and it had revealed it was explorer.exe causing high CPU usage and not a .dll file.

The solution:

Broken icons on desktop. That's it. After reading The Solution i found i had 3 desktop files with no
icons at all. I deleted these three files (two shortcuts, one PDF) and instantly the CPU usage by explorer.exe dropped from a constant 38-40% down to 0.2%

I was wondering if someone or Microsoft might be able to clarify what causes this to actually happen?

Thank you
