High CPU usage when doing barely anything
-
@mib2berlin How many of your 12 Vivaldi installations actually use the calendar?
-
@pointed-stick
Hi, not all of them use the calendar but all use calendar or mail on Windows and Linux.
I use Gmail and Vivaldi calendars, sometimes both sometimes only one for testing.
You have no calendar account added and CPU usage is high but if you disable "Mail, Calendar and Feeds" it goes down?
Makes no sense to me but maybe other user or a mail developer can clear that up.
I can try to poke a mail developer at Monday, they read only the Mail and Calendar section.
We have some reports in the bug tracker about high CPU usage but no tester or developer could ever reproduce it.
I had such an issues some time ago with adding a feed, removing and adding again solve it.
I never could reproduce this again. -

Hi again, can you try this in a new profile?https://help.vivaldi.com/desktop/tools/user-profiles/
3 installs with mail, calendar and feeds:

@mib2berlin I tried an empty profile: load goes to zero, as soon as the window with the main profile is closed. Load does not go up, when Mail and Calendar is enabled in the empty profile.
So, it's a problem with my profile.
Well, I was planning to move from Liferea to Vivaldi Feedreader and from Opera 12 to Vivaldi Mail.
Instead, I'll be looking for a suitable (and hopefully stable) calendar software to replace Vivaldi Calendar with (which I was very slowly warming up to)...
Any suggestions?

@pointed-stick
Aha, it depends on your setup but I get a new profile up and running in a few minutes with the sync feature.
I reset my profile several times over the years, that is maybe the reason I never have issues in Vivaldi.
Fine tuning take some time and you can copy data not synced manually.
No idea about another calendar app, I use only Vivaldi. -
I guess, there is still no feature to "sync" (or backup) to a local space?
It would have been nice, if the "Export Calendar" had done anything before I deleted it...
-
@pointed-stick
No but your personal data are really save and encrypted on the Vivaldi server.
You can remove all data if sync is finished on the new profile. -
@mib2berlin
You can do all that manually but you don´t know which files are corrupted.
I guess it should be save to start with passwords and bookmarks for example, then session and so forth. -
As it turns out, "Export Calendar" works in Vivaldi 4.3, so that's a regression.
I imported the .ics back into the calendar. No change. Same load.

@pointed-stick
Hi, I test the export/import in Vivaldi 6.2.3105.48 and it work as expected.
I export in one profile and import in another.
Is this a local calendar or a Google/Vivaldi calendar? -
Local, yes. Nothing happens, when I click "Export".
-
@pointed-stick
Hm, I export a vivaldi.net calendar and a local calendar:
Appears, tested on Linux and Windows 11.
Do you select the calendar in the settings?
-
Yes, I did select the calendar before trying to export it.
I tried something else: I started Vivaldi from a terminal, with no arguments. This is what it said during startup:
[30113:30113:0918/192838.685217:ERROR:chrome_browser_cloud_management_controller.cc(163)] Cloud management controller initialization aborted as CBCM is not enabled.

Hi again, can you open a new thread about the export issue, this is a bit of topic here.
I can post my terminal output there.Cheers, mib

Perhaps try rebuilding the Mail Search Database and see if it fixes the high CPU usage.
-
Enable Mail, Calendar & Feeds News if disabled.
-
Open the Status bar with Ctrl, Shift, S if closed.
-
Click the Mail icon. Add it back if removed.
-
Click on the settings icon.
-
And click Rebuild Mail Search Database.
There’s also a nuclear option in case it doesn’t help with the high CPU usage. Be careful on which folder you delete.
-
Simply close the browser and head to this folder and delete the mpognobbkildjkofajifpdfhcoklimli folder provided below.
-
C:\Users\yourusername\AppData\Local\Vivaldi\UserData\Default\Storage\ext\mpognobbkildjkofajifpdfhcoklimli
Vivaldi mail will simply re-index the mail client.

Have a same issue.
Vivaldi uses processor when doing nothing with no tabs opened.
I disabled mail, calendar and news feed, and it helps.
But it is useful features. Hope this can be fixed. -
@ddd356
Hi, if you use IMAP try the solution one post above, delete the mail database folder.
You have to rebuild the search database after the start of Vivaldi.

This is still happening. What I have found:
- With Mail (I don't use calendar) enabled I get CPU usage over 50% (even with no web pages open). Can be with a fresh start.
- If I turn off mail/calender/etc, it stays this high but if I restart the browser it will go back to normal (single digit % CPU usage).
- If I turn mail back on, the high CPU usage returns immediately.

OS Windows 10 Version 22H2 (Build 19045.4046)
JavaScript V8 12.0.267.19Any word about a fix? I can't have the computer running high CPU usage just because I have Vivaldi open in the background but I would still like to use it's mail client.

Hi,
As you may already read,
Some users fixed the problem:- Removing the Accounts
- Restarting
- Readding them
