Vivaldi on KDE Plasma/Wayland no windows

sandover

Whenever I try to load Vivaldi under Wayland, nothing appears. When I start Vivaldi from a console, I can see that the program does load and there are no out-of-the-ordinary error messages -- but no windows appear at all on any desktop or activity. Vivaldi through XWayland does work as expected, however.

I'm using Vivaldi stable 4.0.2312.38 under Kubuntu 21.04 (Plasma 5.22.3). My graphics card is an Intel HD 620.

Here's the command I've run in the console:

vivaldi-stable --ozone-platform=wayland --enable-features=UseOzonePlatform --use-cmd-decoder=validating --use-gl=egl

Here are the relevant flags I've enabled. (It doesn't seem to matter whether I enable Vulkan or not.)

#enable-gpu-rasterization 
#enable-zero-copy 
#ignore-gpu-blocklist

Is there anything else I can try? Please also let me know if it'd be helpful for me to include other pieces of info in this post.

Thanks for your help!

@sandover Chromium Wayland support is experimental and to my knowledge there has been zero work on Vivaldi’s side to make it function. Just don’t use it. XWayland works fine, I’m running it on Gnome Wayland as we speak. I’ve tried getting it to run before, Windows show for me but everything is choppy and the app tends to crash. It’s not worth it bothering with it imo.

@luetage I forgot to mention that I have two computers with the same version of Kubuntu/Plasma -- Vivaldi works on one but not the other. So I'm not sure if it's a hardware issue or something with Vivaldi's config, nor how I would troubleshoot the issue.

I tried editing my original post with this info but apparently too much time has passed!

@guigirl Yes, I do have Plasma through Backports!

This is also the first version of Plasma where I feel that Wayland works well in general. What's a mystery to me is that Vivaldi/Wayland works well on one of my computers but not the other.

@guigirl I tried your simplified command with the latest version of Vivaldi stable (4.0.2312.41) and it still doesn't work . . .

Try to add this option to run vivaldi/google-chrome/chromium
--window-size=800,600

I found there browsers can not startup again if they exiting with window maximum state, so just set the startup windows size makes them works for me

@listenerri - Just to add to your excellent answer, I use KDE Neon as my distro of choice, and have my display setup for 3140x2160 resolution at 200% scaling.

I've found a startup window-size of 1920x1034 works perfectly for this configuration, in both KDE Neon & Ubuntu.

So, I now have this as as my Exec, in Vivaldi's .desktop file:

Exec=/usr/bin/vivaldi-stable --enable-features=UseOzonePlatform --ozone platform=wayland --window-size=1920,1034 %U
