High CPU in IsSandboxedProcess() during video playback.

Pathduck

@kahukura Yes I've used ProcMon a lot. But it's usually for finding file and registry operations, reads and writes and network calls. Don't know how much it will do for CPU issues. But I might take a look.

A dump might be useful, but maybe mostly for finding stuff like memory leaks etc. And a dump is really only useful for the developers themselves, who know the code, analysing it would be waaay over my head...

@lamarca Are you drunk again? Who is Jörg? :smiling_face_with_open_mouth_closed_eyes:

Vivaldi_child.dll is just one of the standard Vivaldi DLLs and it exports the IsSandboxedProcess() function.

lamarca

@kahukura It's the Conky.
People installed the program, Presto needed one single file.

lamarca

@Pathduck No beer!
Jörg is here.

Indeed it has more in common with my first name.

lamarca

Sorry, guys. Let's stay on topic.

kahukura

Yes for sure. I think the theory that some process is called way too often is a good one. But what makes it behave like that?

lamarca

@kahukura In that time, The flash player installed on your OS were almost mandatory. The users from Presto forum installed flash twice. Duplicated plugin caused the 100% of resources.

kahukura

@lamarca I had not much use for flash but was a happy O user since 3.62 (according to my records).

I am confident someone checked that multiple times but if it is so evident why not have another look (for the goods).

I had pending to ask about that and the situation on latest computers.

I have same High CPU problem, so currently I'm using FF for watch media, it has a very different function.

FF keeps around 68°, Vivaldi and Opera Dev around 80/90° because the CPU usage.

Opera Stable seems to be some degrees colder.

Tested on Clean Profiles.
Just noticed that muting the video there is less CPU usage and degrees.

Searching, just read that Chrome uses as much Hardware acceleration as it can, so maybe is something related.

It happens on every video, even on YouTube and even at 480p definition.

It has a dual Graphics and even selecting the NVidia to be used, it uses the CPU, which I don't understand.

In my case, the specifications are:

Intel I5 2410 | 2.6Ghz
Intel HD3000 + NVidia 520M
6Gb DDR3
Hitachi HDD

W7 x64

Wonder if it's because hardware related or newest computers are having same problems, so it's a Bug or Chromium programing.

@Zalex108 Hey, your sys specs was build up to execute lots of instruction per second. If you could provide a link for us. Twitter is resource hog, pause one of those silly videos and check the usage via our Task Manager.

Hello there,

as you might know Vivaldi is Cross-platform, a Linux user can support a Mac and vice versa. I like that part - Mac OS has the sudo command line.
I can see one connection between the threads, resource hog. The thread starter wants the logs, crash logs, I follow his concern.
Lastly, I mentioned here the few number of users posting Cpu and ..... you came to this place.

@lamarca

When playing video I don't use Social Networks, I know they are resource eaters.

Also, I use UBlock and Social and Mining lists blockers.

Link? For the videos? Any on YouTube.

As a detail, even happens on 480p definition.

Despite it's build for lot of process, is old HW.
I don't know for which is Chromium programed.

But the fact is that FF and also Maxton are very low on resources watching videos.

@Zalex108 Hola. They called it that way. I don't join those group of poeple who accept me as a member. I got all the info in one place, politics, undersea cable surrounded by Putin submarine, painting. Only on twitter.
Did you by any chance know how much Vivaldi spends time and resource to load Tw?

Zalex108

@lamarca

No I don't know about Tweeter, nor on other browsers, I'll check.

Pathduck

@Zalex108 Are you able to reproduce the same issue I'm describing in the first posts? Are you seeing high CPU usage in the rendering process caused by calls to the IsSandboxedProcess() function in vivaldi_child.dll? You need to use Process Explorer to look at thread CPU usage in the render process while playing back video.

Are you also able to then run a clean profile and see if the issue is gone there? If not - then it's not the same issue we're having. High CPU could be caused by a thousand different reasons. Nor is this thread about high GPU usage as that's not what I see. I'd really like to keep this thread free of guesswork or conjecture.

I am also only testing this on YouTube videos to keep other causes out of the equation.

Then again, it's my fault, I should've kept the title more specific.

Zalex108

@Pathduck

Ok, I'll check that specifically.

@Pathduck said in High CPU in IsSandboxedProcess() during video playback.:

Set Override software rendering list to Disabled. Current is Default which I assume is Enabled.

ehm, this option overrides Chrome's built-in software rendering list and permits GPU acceleration on unsupported system configurations. I don't think that matters with your GPU but I wouldn't disable it.

Pathduck

@npro Yes, my fault. I meant to say it's set to default now which is Disabled. I tried setting it Enabled to see if it made any change, and it didn't.

Do it, @Zalex108 , don't forget they run an outdated engine.
bye or have a nice day, it depends on your TZ
