Whatsapp web on web panel became extremely slow

Hi, the WhatsApp issue is known, there are some threads about.
I have no idea if one had report it to the bug tracker.

https://forum.vivaldi.net/topic/78815/whatsapp-web-on-web-panel-became-extremely-slow

Vivaldi run as fast as Chrome, Edge on my systems (Windows 11 Pro, Linux), except of the startup time but this is because of the second UI layer and will not change. My system specs are in my signature.

Did you restart Windows after removing Sophos?

Cheers, mib

@Yukora I can not help here with issue Window hardware config and drivers are different from Linux. Please aks at https://forum.vivaldi.net/category/32/vivaldi-for-windows

DoctorG

@crossLain Intel HD 520 is a older GPU?
Do you use any driver optimisation?
Have you updated Intel firmware and microcode?
Is the GPU driver from Intel?
Do you use an settings in vivaldi://flags?
Do you use command line parameters with Vivaldi?
Had you tried to update codecs for Vivaldi ins shell with
sudo /opt/vivaldi/update-ffmpeg

I can no really tell what it is. Perhaps the Mesa driver.

Sorry, you should wait until a Fedora Vivaldi user can tell more.

DoctorG

@Artusundschnitzi Which graphics card/GPU do you have?
Which Vivaldi version?
Updated BIOS and firmware?
Latest GPU driver from chipset/GPU card manufacturer' website?

Perhaps there is some trouble with GPU driver and animated UI.
Try this for a fix: In Settings → Appearance → disable Used Animation for UI, restart Vivaldi.

@Artusundschnitzi Intel CPU/GPU?

Yukora

This is still not resolved, whatsapp web is unusable in a web panel

Vivaldi 5.4.2753.40
PC, Windows 10
extensions: Privacy Badger, uBlock Origin, Twitch Adblock, LastPass
No special antivirus installed
GPU up to date

Disabling all extensions and restarting Vivaldi did not help, still stutters and freezes so probably not related to extensions

(Also happening on Linux)

@Yukora said in 100% Cpu usage on web panel use (whatsapp web):

Disabling all extensions

Disabling is not the same as "using no extension".
Check in Guest profile to see if a extension or Vivaldi Blocker causes this.

Sometimes older hardware causes high CPU usage.

Yukora

@DoctorG Still stutters even in a new profile - also freezes when writing messages

Is not extremly slow for me, but slower.
I do not know if Meta has changed something in web ui of Whatsapp the last weeks since last Vivaldi 5.4 update.

I have the same problem, exactly the same. I love Vivaldi, it is my daily browser, but I also use WhatsApp as a business tool, and it has brought me many problems, to the point of having to reinstall Opera to be able to work quietly, it's a shame, Vivaldi has come to less in these last updates, resource consumption is excessively high and every time they add more features that make it terribly slow, now not even with a Dell computer with 16 GB of RAM, Core i7 processor 11 generation, nor with SSD 480 GB is possible to see speed, it is simply a turtle with a sea of latency, just horrible to use. What a disgrace.

Whatsapp web here is also completely unusable. It crashes and it is extremely slow. The problem persists whether I'm using on the side panel or as a normal tab. I tried removing cookies and disabling extensions, but it did not help.
Also tried on Edge and it works fine.

Hope it gets fixed soon.

@DoctorG Well I installed Opera and it seems to me that it is not a matter of graphics card or updates, since Opera works in a real wonder, fast, agile without lag, if you tell me that to use the panel smoothly with Vivaldi, I need to have a video card with high performance on a laptop, well great, but I sincerely believe that it is a problem of how Vivaldi manages resources, with the latest updates Vivaldi is getting worse, with each function that are adding other worsen, consumption to open it is even slow and puts the slow computer, which does not happen with Opera, I have had to reinstall it with sorrow. I even formatted my computer to check if it was an issue of my computer and the surprise is that NO, the problem persists.

nellmf

@mib2berlin Yes, I restarted the computer, even reformatted my laptop, updated firmware, drivers, etc, etc, etc. As I said I installed Opera and it works perfectly, the problem is directly the management that Vivaldi does, but not only that, since version 5.x, with many changes unfortunately Vivaldi has become less in my daily use, a browser that consumes almost 1GB and a high percentage of the processor does not become efficient in time because it slows down the computer in general, if I close it the inconvenience is over.

@nellmf
Hi, I don´t use WhatsApp, I kicked it some moths ago.
Something goes really wrong with the your system and the Vivaldi combination.
I have several systems with Windows 11 and Linux running Vivaldi fast and not resource hungry, no idea why it not work out for you.

One have sometimes go further if a software waiste more time than it is useful.
I am very sorry if you leave Vivaldi but they ever come back.

Cheers, mib

Experiencing the same thing. Macbook pro 13" 2020
Works well as a regular tab.

I change WA to a tab:

1.- The slowness is gone.

2.- The problem with videos is still present.

I do not understand why my Vivaldi 5.4 Stable runs smooth with Windows 11 + GT 710 & Debian 11 + Intel Xeon E3-1200 as webpanel for WhatsApp and yours not.
