 |
|
Hi,
I'm experiencing high CPU usage (nearly 100%) when using browsers like Firefox and Google Chrome on my Gentoo system. This happens during web browsing, scrolling, and the issue persists whether hardware acceleration is enabled or disabled. I’ve verified that hardware acceleration works via `amdgpu_top`, but it hasn’t made a difference.
My system specs:
- CPU: Ryzen 7 8845HS
- GPU: Radeon 780M
- RAM: 16GB
- Kernel version:Linux 6.12.16-gentoo-dist
I’m using Wayland as my display server.
Here’s the output of `emerge --info`:
| Code: | Portage 3.0.66.1 (python 3.12.9-final-0, default/linux/amd64/23.0/llvm, gcc-14, glibc-2.40-r8, 6.12.16-gentoo-dist x86_64)

Steps I’ve tried:
1. Enabled and disabled hardware acceleration in the browsers.
2. Looked at tabs and extensions via the browser’s task manager, but found nothing suspicious.
I’m not sure what else to try. Any help or suggestions would be greatly appreciated.
Thanks,
dzerokira
