Weird CPU usage in idle

[rheaSaturn]

Is it normal to have the browser using 10~15% of CPU usage even while in idle? Tried disabling all extensions and nothing changed.

I am having the same issue. Mercury is using 18% on idle. Windows 10, Ryzen 3600, mercury_122.0.2_win64_AVX2. I tried older version and still was ~20% cpu load on idle. Deleted all profiles and cleared startup cache. In the about:processes the Data Decoder (2692) process shows 59MB ram and 100% cpu usage. I cannot find a solution. In Thorium, Edge or Firefox CPU is 0-1% on idle.

On my other pc, ryzen 5600G, windows 10 this doesn't happen.

same issue. Mercury is using 10% on idle. Windows 10 22H2 19045.4046, Ryzen 7 5800H, mercury_122.0.2_win64_AVX2. In the about:processes, process "GPU" using 100% cpu.

Same here. Data Decoder thrashing my AMD Ryzen 7 5800X. Using mercury_123.0.1_win64_AVX2

Same here, Win Server 21H2, mercury 123.0.1 win64_AVX2. I solved this problem by disabling NVIDIA Display Container LS service

Will that in any way interfere with the NVIDIA Control Panel? Did not work for me.

I have the same issue here. As you can see. Nvidia is somehow causing this weird cpu usage. I tried to update drivers etc. Nothing helped.

I have Notebook and setup with 1 additional monitors over USB-C. Dunno if thats relevant here.

Update: this worked

Also having this problem. On all builds of 123.0.1 (SSE3 - AVX2) and 115.4.0 Win 10 and Win 11. Nvidia GPU.
