High CPU usage when doing barely anything

brianrubin

Yup, still high CPU usage.

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.

@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.

@megosu said in High CPU usage when doing barely anything:

It has been like this since I started to use Feeds in April, no matter the updates.

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 ?
