High CPU usage after update 6.2.3105.45

[Nova1112]

Hello

It seems to me that after the update to 6.2.3105.45 (stable channel, 64-bit) Vivaldi began to tire my CPU unreasonably. I noticed this by its temperatures when Vivaldi stays open (also clean Incognito window). My CPU is then continuously at 30-40%.

Know of any problems?

[Nova1112]

P.S. Of course, these 30-40% are generated by the Vivaldi processes themselves

[DoctorG]

@Nova1112 Check with internal Vivaldi Taskmanager (hit Shift+Esc) which tabs and or extensions cause so much usage.

@Nova1112 An other idea, problem with older GPU and driver and hardware accelereation.

What is shown in page vivaldi://gpu?
Use "Copy Report to Clipboard", in reply hit the </> button and paste the report here.

All graphics drivers up-to-date from manufacturer's website?

"Application: Vivaldi"
and
"Browser"

Once one, once the other.

I haven't touched the drivers - but that's not a problem - I can update them.

Unfortunately, I have to break the post into parts because I can't send it.

Available
[Default Toggle Names]
lazy_clear_resource_on_first_use: https://crbug.com/dawn/145: Clears resource to zero on first usage. This initializes the resource so that no dirty bits from recycled memory is present in the new resource.
use_temporary_buffer_in_texture_to_texture_copy: https://crbug.com/dawn/42: Split texture-to-texture copy into two copies: copy from source texture into a temporary buffer, and copy from the temporary buffer into the destination texture when copying between compressed textures that don't have block-aligned sizes. This workaround is enabled by default on all Vulkan drivers to solve an issue in the Vulkan SPEC about the texture-to-texture copies with compressed formats. See #1005 (https://github.com/KhronosGroup/Vulkan-Docs/issues/1005) for more details.
vulkan_use_d32s8: https://crbug.com/dawn/286: Vulkan mandates support of either D32_FLOAT_S8 or D24_UNORM_S8. When available the backend will use D32S8 (toggle to on) but setting the toggle to off will make it use the D24S8 format when possible.
vulkan_use_s8: https://crbug.com/dawn/666: Vulkan has a pure stencil8 format but it is not universally available. When this toggle is on, the backend will use S8 for the stencil8 format, otherwise it will fallback to D32S8 or D24S8.
use_placeholder_fragment_in_vertex_only_pipeline: https://crbug.com/dawn/136: Use a placeholder empty fragment shader in vertex only render pipeline. This toggle must be enabled for OpenGL ES backend, the Vulkan Backend, and serves as a workaround by default enabled on some Metal devices with Intel GPU to ensure the depth result is correct.
use_vulkan_zero_initialize_workgroup_memory_extension: https://crbug.com/dawn/1302: Initialize workgroup memory with OpConstantNull on Vulkan when the Vulkan extension VK_KHR_zero_initialize_workgroup_memory is supported.
vulkan_use_image_robust_access_2: https://crbug.com/tint/1890: Disable Tint robustness transform on textures when VK_EXT_robustness2 is supported and robustImageAccess2 == VK_TRUE.

Ok, that's all, and I'll update the GPU driver in the meantime.

[Nova1112]

I already have the current GPU driver - it didn't help

I am having the same exact issue. Notably, when I open it with someone else in the "Who's using Vivaldi?" window or run vivaldi in guest mode, the problem does not occur: it only happens with my own profile. Not been able to figure it out so far, and I've tried disabling all of my extensions, which didn't work.

EDIT: I am on Linux, rather than Windows, but the issue seems to happen on both operating systems.

[DoctorG]

Do you use Vivaldi Mail/Calendar/Feeds?
In the past here was a issue with Vivaldi Mail client in 6.1 Stables.
For a test: disabling Vivaldi Mail in settings solved it.

But i can not check, i do not use Vivaldi Mail client.

[zauberin]

@DoctorG Disabling Mail/Calender/Feeds fixed the issue, though I had to close and restart Vivaldi in order for the high CPU usage to disappear.

Seeing as the problem seemed to be sucking up all the power on one CPU core, it makes me wonder if the problem was a thread getting caught in an infinite loop or something.

[DoctorG]

@zauberin I thought such Vivaldi Mail issue was fixed in a 6.1 Stable before. Strange.

//edit: I tried to ask internally, but it is late and no dev in cat of office anymore.
Sadly you have to wait until the next days.

@DoctorG said in High CPU usage after update 6.2.3105.45:

Yes! Unchecking the checkbox:
"Enable mail, calendar and RSS feeds"
Solved the problem.

But it was not known what caused it (email, calendar or RSS feeds). So after deleting the RSS Feed that I had saved, the CPU usage was back to normal I don't know if it's the fault of too frequent refreshing (I had it set to 5 minutes) or the RSS function at all, but since I don't follow any channel - the problem doesn't occur anymore.

Thank you all for your help

[DoctorG]

@Nova1112 Ah, it was a RSS feed causing this and you deleted the feed subscription?

[DoctorG]

@Nova1112 Can you tell the URL of the feed, for a test if that happens to me, too? If yes, i would report that as a bug internally.

[Nova1112]

@DoctorG It's a personalized link that I don't want to share on the forum, I'll send it to you in chat.

[DoctorG]

@Nova1112 The feed is ok and i could not see any issue with Vivaldi Mail in 6.2 Stable. All ok, no high CPU usage.

[anecaslu]

I was facing the same problem. I realised that I have a very high CPU usage from Vivaldi. Firstly I though it could be that i have several tabs open, but that wasn't the problem. The problem was that I have a RSS feed. I tried deleting it from Vivaldi's settings and now it works perfectly, as usual.

The RSS feed was this one, but I think the problem would be with any feed: https://stajvalencia.blogspot.com/feeds/posts/default
