Why com.apple.Webkit.GPU consuming a significant amount of CPU?

Hi there!

I just switched to an Apple Silicon Mac Mini M2 Pro from Macbook Pro Intel 2020 and noticed that the process "com.apple.webkit.GPU" is consuming a significant amount of CPU and memory, according to screenshots below.

It incresing consume continually

The things is I haven't been using Safari and that your main applications are Chrome,Safari, Visual Studio Code, iTerm, Fig terminal extension,Logi+ and other stuffs for web development (brew php mariadb composer npm node nginx....)

Is it possible to track down the origin of this process since I haven't encountered it on an Intel-based machine previously and installed application are identically with my Macbook Pro Intel 2020 ?

Mac Mini M2 Pro - Ventura 13.2

Mac mini, macOS 13.2

To me, this happen because I had another Mac user that had Safari open, I had to logout my current user and login to my user where I had Safari open, close everything and logout (not lock screen) from that user then come back to my regular user and the com.apple.Webkit.GPU process was gone. Hope this helps in this mystery.

FYI: The way how I find out this, was when I double click on the com.apple.Webkit.GPU process, I noticed that the "User:" shown was my other Mac user.

Same here. But a bit worse.

Not using Google Chrome, just plain old Safari.

iMac 27" 2020, Core i9, 64 GB, AMD Radeon Pro 5500 8 GB running Big Sur, then upgraded to Ventura last week. BAM! Safari significantly slower (noticeable lag) and com.apple.WebKit.GPU at +100% CPU (while consuming ±290 MB of RAM and 0% GPU (what gives?)).

You’re holding it wrong.

😆😆😆

Sorry, I can't be serious about it. Many people have this pro™blem, and it seems like no<body> at the company cares. Really sad. It's somewhat better under 13.3.1 (22E261), but not yet fixed.

Update: after manually forcing com.apple.WebKit.GPU to quit, CPU went back to normal. But why is it already taking ~37 GB of virtual memory?

This metric seem to not be correct. Or is it aggregating all virtual memory size allocated by its parent (launchd) and other child processes?

It smells like a memory leak. Or a poor garbage collection mechanism.

Just because there are few cases, it is not so important?

Is that what you're trying to say?

How large will the number of unreported cases be?

I have this problem and it came on sort of suddenly - now the fan is running all the time. What is this?

When I try to look up that link, my entire screen is covered with which operating system are you using? And will not allow me to choose or move the paste. Can’t see information. It’s infuriating. Some kind of third party unknown developer that has been stalking me.
