How to enable hardware acceleration & WebGL in Vivaldi on Pi4?

Botspot

I am a Vivaldi enthusiast and would like very much to switch to it completely.
But, many of the websites I use require WebGL.!
I can't even play the Vivaldia game.

But it gets worse than that. Vivaldi does not appear to be hardware accelerated at all whatsoever.
Browsing (and particulary scrolling) is laggy, jerky, and prone to screen tearing. YouTube is unplayable, and forget about editing any 3D files on TinkerCAD.

According to vivaldi:gpu, there really isn't any hardware acceleration going on at all.

Compare this to Raspberry Pi's official Chromium browser.

Well that explains why it runs so much smoother.
Any ideas?

MondQ64

Bump! Same question here.

@botspot Any error messages in starting in shell with vivaldi

Yes. It displays the exact same error as before.

Hi,

Try enabling vivaldi://flags/#ignore-gpu-blocklist

I've seen it involves OpenGL, about WebGL I don't know if would be different on that system.

Nothing changed.

Same errors in the terminal as before.

@botspot

Oh,

Here worked.

So I don't know.

@zalex108 I'm not the only one having these issues.
Other people are too. See: https://forum.vivaldi.net/topic/51507/vivaldi-cannot-load-libglesv2-even-though-available/6
Maybe all of us could compare notes and figure out what we all have in common?

No idea in general about the Pi and ARM but according to this message

Failed to load /opt/vivaldi/libGLESv2.so: /opt/vivaldi/libGLESv2.so: cannot open shared object file: No such file or directory
Failed to load /opt/vivaldi/swiftshader/libGLESv2.so: /opt/vivaldi/swiftshader/libGLESv2.so: cannot open shared object file: No such file or directory

have you actually checked if those 2 files do indeed exist in those locations?

craigevil

What is the difference between arm32 that Botspot posted and mine running Pi OS arm64?

Botspot

@gwen-dragon Exactly. I noticed that too.
Both files exist, but Vivaldi thinks they do not.
https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=311290

Here is the output for running the file command on both of these problematic files:

pi@raspberrypi:~ $ file /opt/vivaldi/libGLESv2.so

These files do indeed exist, but for some reason Vivaldi can't seem to detect them!

Botspot

Just in case this was an issue caused by my system or setup, I flashed a brand new Raspberry Pi OS 32-bit to a high-quality SD card.
I booted the OS.
I downloaded and installed the latest Vivaldi armhf deb file.
I launched Vivaldi from the menu. No WebGL, just like before.
I closed Vivaldi.
I ran Vivaldi in the terminal:

And yes, despite the errors, /opt/vivaldi/swiftshader/libGLESv2.so and /opt/vivaldi/libGLESv2.so do exist.

@botspot What if you symlink those libraries to those of your system instead (that is if you have them installed via their corresponded packages) ?

Seems like there's something wrong with the 32-bit version of those -maybe deprecated?- for ARM or x86, as @craigevil and others have shown not to be plagued by that.

Botspot

@npro I'll try symlinking libs soon.

For now, I tried running Vivaldi using strace. This logs every system call and will pick up every attempt to load a library. Maybe it will indicate a missing .so file.

Below is a strace output that has been filtered to only display all failed attempts to load any .so file. I assume most of these errors are harmless, because chromium-browser produces a similar strace output.

The only info I get running Vivaldi from a terminal is:
vivaldi
[11224:11224:0513/181035.712224:ERROR:sandbox_linux.cc(374)] InitializeSandbox() called with multiple threads in process gpu-process.

Strace and the file commands output the same info as Botspot.

Did I mention I had changed several Flags?

Did I mention I had changed several Flags?

@craigevil If you disable all those flags, does vivaldi:gpu still display WebGL on your arm64 system?

Nope.

@zalex108 I'm not the only one having these issues.
Other people are too. See: https://forum.vivaldi.net/topic/51507/vivaldi-cannot-load-libglesv2-even-though-available/6
Maybe all of us could compare notes and figure out what we all have in common?

Hi,

You can ping there and ask.

Forgot to mention that the Flags I've mentioned, are working in a non ARM System, so maybe it's different for those ones.

The output of vivaldi:gpu
https://paste.debian.net/1198004/

Everything works. However watching Youtube videos in the browser causes the cpu temp to go sky high. Normally the cpu temp on my pi400 is between 35-50, watching a youtube video for just 10 minutes and it jumped to 70.

So yes opengl works with the proper flags but it also causes the PI to go nuts.
Neither Chromium nor Firefox cause the same issue.

Better off not messing with the flags.
