[bug][solved] High CPU of "App:Vivaldi" due to RSS feeds

Here I use CCleaner as well for deeper clean up.

Replace Paths with own installations

I've made a copy of my profile, of course.
I've tried additional things but no success: Not just deactivated but also removed all extensions, removed all my bookmarks, removed all feeds and disabled "Mail, Calender, Feeds", deleted the Cache folder manually (I think that's why the tabs are not showing no title text anymore and I can't close them by clicking the X anymore). Nothing worked so far.
I will try and purge my profile using those paths.
-
There's not another Task Manager to see what processes are involved.
On V it's Shift+Esc
Maybe the ProcessExplorer or ProcessHacker gives some more info.
They're both on PortableApps too. -

Ok, I found it. It was the RSS feeds that were hogging so much CPU time! I had only two: one with 89 messages and the other with like a dozen or so. That's weird.
First I had to delete the RSS feeds and only after restarting Vivaldi the App:Vivaldi went down to 0.1 CPU time.

You can try readding it
Some issues with Mail/Calendar/Feeds gets fixed by this.
Otherwise,
Try changing the Update interval. -
I'll just not use Mail, Calendar or Feeds in Vivaldi. I haven't really used it before, won't use it in the future. I've been a Mozilla Suite user back in the day, and I really started to dislike bloated all-in-one web suites, even in the old Opera I found it was slowing down performance a lot. Once bitten, twice shy. So I try to disable all this extra stuff and wasn't that happy when Vivaldi started integrating all this junk back into the web browser.
But for completeness sake I've tried readding one of the feeds and the high CPU usage is back. So to me this seems like a serious bug. I'm just glad it's not a bug in a core feature like history, extensions or bookmarks.

You could either share the URL if you like for others to test and/or report it for the Devs check.
It may be the Feed itself.V tries to have the same features as Opera Presto had and modern ones.
Having them disabled just puts a bigger size on the installer, its performance shouldn't be affected. -

Sure: https://feeds.feedburner.com/HaveIBeenPwnedLatestBreaches and https://www.understandingwar.org/rss.xml
But I've added another RSS feed as a test, https://newsfeed.zeit.de/index and I got the high CPU again. I guess whatever feed I add the bug will come back. So I don't think there's anything special or wrong about those feeds at all.

There's some other reports that needed to delete a folder and Profile
Default\Storage\ ext (that one and its content)
This rebuilds Mail and Feeds--
I had that problem too tome ago but not now with Mail and some Feeds.
Did both options and spent some time without them on V
After some updates tested again and the CPU is normal.--
I've added that Feed you've shared and n a Clean Profile and had no CPU problems.
I'll see on next days

This rebuilds Mail and FeedsThanks. I can confirm that this fixed the problem. Followed RSS feeds don't hog the CPU anymore.

I'm noticing quite a difference in responsiveness of the UI and startup time since I've deleted that Storage folder. Interesting how purging an old folder can have such an impact.
