High CPU usage when doing barely anything

[brianrubin]

Removing the feed and restarting the browser gives me normal usage levels.

[DoctorG]

@brianrubin And with the feed the issue is back?

[DoctorG]

@brianrubin Caan you please open Settings → Feeds , select the feed causing the issue and copying the address and post here.

[brianrubin]

@DoctorG Same feed as mentioned before.

[DoctorG]

@brianrubin Please, the URL! I do not know if we tested both the same feed!

[DoctorG]

@brianrubin Please report issue with Laptop to Vivaldi bug tracker.
tell them precisely about the issue, your hardware, the broken feed URL.
Perhaps teh devs they can check!

[DoctorG]

@brianrubin Bye, until tomorrow. Too hot now at 19 o'clock European SUmmer Time with 31°C. Puh.
I leave my office.

[brianrubin]

@DoctorG Apologies, it was this one:

@DoctorG Will do, thank you!

Same here, I found out today that disabling feeds (and calendar and email) solved my CPU usage problem with Vivaldi.
It was bothering me for some months, without knowing why, but today I was fed up and I took the time to investigate.

I don't use calendar or emails modules in Vivaldi, but I use Feeds, and it seems to be the culprit. After disabling these modules, CPU usage ("Background page" process in Vivaldi used around 70% and above) is fixed.

Any clue why this issue exists ? It has been like this since I started to use Feeds in April, no matter the updates.
FTR, it is still happening with 6.9.3447.37.

One/more of subscriptions could be broken or one feed in list has broken content.

My idea: export all feeds as OPML file, delete all subscribed feeds, import from OPML file. (not tested)
See menu File → Export and File → Import from Application or Files
https://help.vivaldi.com/mail/mail-feeds/import-feeds-from-other-feed-readers/

@DoctorG this could be a workaround, but how can we submit this bug to vivaldi team ? A proper fix would be best.

[DoctorG]

@megosu Export the OPML file, report issue to Vivaldi bug tracker and add as zipped file to report.

@DoctorG I just tried the following:

• Feeds enabled, but no feed added: CPU usage is normal (very low)

• One feed added (https://downloadcenter.trendmicro.com/pull/feed/product/91?): CPU usage rises, see screenshot, and persists even if I remove the feed. Once the feed is removed, I need to relaunch Vivaldi to get back to normal.

• Another feed added (https://www.cert.ssi.gouv.fr/avis/feed/): same behavior.

It doesn't seem to be related to these specific feeds, do you experience the same issue ?

[DoctorG]

@megosu All is nice on my 6.9.3447.37 Win 11 23H2.
Tested with 6.9.3447.37 and added as feeds:

Which CPU/GPU do you have?
Which external security/privacy tools?

[megosu]

@DoctorG intel integrated GPU HD graphics 530
Trend Micro Apex One

[DoctorG]

@megosu

intel integrated GPU HD graphics 530

I asked for CPU/GPU because some users has such issue with AMD hardware.

Trend Micro Apex One

Perhaps blocks your security solution the feed scan/fetching.

Is Vivaldi used in a company environment?

@megosu
Hi, testing both feeds but cant reproduce high CPU usage on Windows 11, Vivaldi 6.9.3447.37.
Did you update VIvaldi today?
I would check this in a second test Profile to exclude extensions and/or profile issues.

Cheers, mib

Hi @DoctorG @mib2berlin ,
I tried several things:

• disabling AV
• closing all my tabs and keeping only 1 workspace
• start with --disable-extensions
• start in Private mode
  I always have the same issue.

Only time I have managed to avoid this issue, is to create a new profile.

My next move, is to try with my profile on another computer with a fresh install.

What else could I do to fix it ?

This only work partially, some files and folders are encrypted.
Do you use sync?
It's really the best method to start from scratch.
Sync your default profile, sync your second profile and test there.
If all is working there you can make it your default profile.
