High CPU usage when Vivaldi mail is running

v.lagadec

Hello !

Whenever I use Vivaldi, my mail account is running in background, but it uses approximately 40~55% of CPU usage even when I'm not doing anything on my computer. I tried out two different mail accounts, same issue.
If I disable the mail/calendar service and restart Vivaldi, or if I remove my mail account from Vivaldi and restart the app, the high CPU usage is gone.

I don't really know what's happening, but I can provide some other things if required to understand what's going on. Can you help me on that one pls?

Vivaldi 7.0.3495.18 (Stable channel) (64 bits)

Hi, we have several threads about this issue but there is not a clean solution.
The Vivaldi developer never could reproduce it and I use 5 accounts with no CPU usage.
Does it us 50% CPU in the internal taskmanger or the system task manager?
You can only remover the accounts, delete the mail database and add them again.
Or delete the database and restart Vivaldi, it is located in your profile folder "Default", delete the foder:

\Default\Storage\ext\ mpognobbkildjkofajifpdfhcoklimli

Both pics from the task managers were when the default mail configuration was done, and now that I deleted

\Default\Storage\ext\ mpognobbkildjkofajifpdfhcoklimli

It's now down to 0~10%
(kinda the same in Vivaldi task manager)

So, I restarted Vivaldi, added another mail account, and now it seems to run just fine.
Thanks for the quick response, now I may use Vivaldi mail instead of Outlook or the regular web mail client. Thanks !

That's interesting... I've got two machines where mail uses more CPU than it should and on one of them I actually went from a snapshot install (where I was testing mail) to a stable install and it exhibited the same high-CPU behaviour.

On the other machine I added mail to two different user accounts and both of them show high CPU usage when mail is active (I got into the habit of deactivating mail unless I need it on that laptop).

So all my evidence says it depends on the system and wouldn't be fixed in the way you describe.

@mossman
Hi, did you remove the accounts and delete the mail database?

My post talks about one case where it's a completely different install and another where it's two different Windows users... absolutely no common user files at all!

Hello! I am experenceing the same thing however my mail options are turned off.

When I first open vivaldi it takes several minutes for me to even do anything, I have sit and wait for it to load. I can't even miminuze the browser. I uninstalled it and re-installed hoping to see if that would fix anything it didn't. I deleted my internet browsing history besides a few things like my downloads,cache. That still didn't work.

I was able to get on a guest profile and it seemed to work just fine. I have a strong feeling this has to do with the vivaldi sync being down. I also didn't have this problem till the sync stated messing up. I have some pictures i can share when it works.

Vivialdi 7.0.345.26 (Stable Channel) (64-bit) windows 10.

Hi, a user report 3 minutes start time cause by extensions.

"Powerful Pixiv Downloader" and
"Pixiv Fanbox Downloader" very long start time of Vivaldi.

But it could be any extension, disable all and test or start Vivaldi without. Edit your Vivaldi desktop shortcut with --disable-extensions

I'm getting super high CPU usage as well, and it's killing me. It keeps my laptop hot when it's plugged in, and it drains my battery otherwise.

OS: macOS 15.3 (24D60)
Vivaldi: 7.1.3570.47 (Stable channel) (arm64)
I know for sure that it happens with Gmail.
I disabled all extensions and that doesn't help.

To cope, I'm disabling the "Enable Mail, Calendar and Feeds". When I want to check my mail, I click it again, let my mail download, and then disable it again (and restart the browser... it doesn't stop taking high CPU usage until I restart the browser).

I've tried deleting my account and adding it again, and I've had this problem for at least several months worth of Vivaldi updates. I just tried deleting the account and trying again, and the high CPU is still happening.

Help please.

@jfeiablc do you have some more info about your setup? For example, when have you first set up your accounts, how many messages do you have in them, what makes you think Gmail is making things worse, do you have some antivirus program or file indexing programs running that might lock files for Vivaldi?

Does the same happen if you set up the same accounts in a fresh user profile?https://help.vivaldi.com/desktop/tools/user-profiles/

jfeiablc

@WildEnte Of course!

I don't think Gmail makes it worse, I just know it happens when I use Gmail. I have another account that is a pain to set up that I thought might be the problem, but it's not. I haven't set it back up again.
When I set up Gmail, it's super easy and works immediately; that's why it's a good example to reproduce the issue.
I use all the defaults for the mail config. So (e.g.) the number of messages downloaded are just those received in the past month. I only have 3 in my inbox currently.
I don't have any antivirus software running.
md_stores (the macOS indexer) does run sometimes, but it really has no correlation to Vivaldi. It only runs at sensible times (externally powered, at night, etc).

I tried creating a new Vivaldi profile and enabling mail there. And it worked! Here's what I did:

I created a new profile. And kept Vivalid open for both profiles.
In that profile, I enabled mail and set up Gmail. Up to the point where I finalized my name and settings and clicked Okay (before the "Great you're all set!" dialog), I had no additional CPU.
As soon as the "Great you're all set!" dialog was shown, CPU usage shot up for a while, and then went back to something like normal.
I clicked "Open mail" in that dialog. CPU jumped up slightly and then went back to normal.
Aaaaand it's all normal!

A clue! What does this tell us?

WildEnte

@jfeiablc well apparently the issue is connected to your standard profile. The next step would be to try and figure out what.. but how is a good question. I've been in this situation a few years ago and ended up moving everything to the new profile where my CPU didn't go nuts.

@WildEnte
Hi, in a thread @Pathduck told the user to delete all except the profile folders in \User Data\Vivaldi and this fixed the user issue.
Will try to find the thread.

Cheers, mib

Pathduck

@mib2berlin That topic was about not being able to download components (permissions issue most likely), so deleting all folders deletes all installed components and forces a redownload.

It has nothing to do with high CPU

Besides, didn't the user say the problem was solved?

mib2berlin

@Pathduck
Hi, solved in a clean profile yes.
Make not much sense if I think again, so @jfeiablc has to start from scratch, I fear.

Cheers, mib

@jfeiablc re-reading this thread I see a hint from @mib2berlin above, which you can try first before setting up an entirely new profile:

Yeah, okay. I'll just set up a new profile if that's what it takes. But man, it's a bad sign. I hope I don't find it start taking a ton of CPU just because I have a power of two bookmarks or something.
