Vivaldi fails to run with GPU acceleration

@vistaus
Hi, can you may check with an actual Chromium or Chrome vwith the same or higher verion number.
It doesent help you much but you can see if it is a Vivaldi only problem.
I use Intel HD 520 at moment without issues, hm.

Cheers, mib

I just installed Chromium and it starts just fine with GPU acceleration enabled, so the issue definitely seems to be Vivaldi-specific.

@npro I installed Chromium 91, so same.

@rogerwilco But how does that help my issue? Can anyone from the Vivaldi team jump in? 'Cause Vivaldi is pretty unusable without hardware acceleration

How does it help you assess the situation? How about other data points, such as another Debiad-based OS, nVidia driver used, output from vivaldi://gpu.

If you want to communicate with the devs, then maybe open a proper ticket, including your hardware specs, kernel & driver info, extensions installed in Vivaldi, said vivaldi://gpu output from your PC et al. I'd have my doubts that they'd be spending much time on the forum.

Anyway, good luck and success.

@rogerwilco As I said in the OP, I'm using the Intel driver - I don't even have an nVidia card.

Also, as I pointed out: I can't reach vivaldi://gpu properly, so there's no way to post anything from that page. And as you can see, I already confirmed that the issue is not present in Chromium 91 (same version as Vivaldi is based on).

I cannot currently test another Debian-based OS, but I've been using Deepin for a long time now and this issue only started in the previous snapshot.

Vistaus

Just updated the snapshot and the issue is still present

Vistaus

Alright, so I reinstalled Deepin from scratch and installed a fresh install of Vivaldi Snapshot, but the issue is still not solved

What else could I try to solve this?

@gwen-dragon Yes, for me too - stable version (4.0.2312.33-1). It has many errors on run. Only main window opens without any content (with white background). Some of errors on run are:

Errors:

@coronium Well, I managed Vivaldi to properly open by removing Default folder... I still do not know what exactly happened...

luetage

@coronium Maybe your session got borked. I would backup the current Default folder, delete it and put in the old one. Then open the folder, remove session storage and try to start. Worth a shot.

coronium

@luetage Yes, on that way I recreated folders and Vivaldi became functional. Thanks.

coronium

@coronium Hm, at the end the Skia renderer made me a problem:
Skia API for compositing
If enabled, the display compositor will use Skia as the graphics API instead of OpenGL ES. – Mac, Windows, Linux, Chrome OS, Android:
chrome://flags/#enable-skia-renderer

coronium

@gwen-dragon Weell, when it was the default value it wasn't working, therefore I needed to discover it by myself and to turn it off manually

coronium

@gwen-dragon That's true. Now is an old Radeon (Cedar HD 5000/6000/7350/8350) with open-source driver the case... :-|

Vistaus

This issue is solved since the latest snapshot: it now runs with GPU acceleration enabled again. This was confirmed as a Vivaldi bug, so it definitely wasn't on my end, even though a few persons here tried to spin it that way. Anyway: thanks Vivaldi devs for (finally) fixing it!

coronium

@vistaus Hi, do you have some exact reference/link to investigate it further? Tnx.
