Getting a very frequent warning about an undefined "toString" from wayland

Issues & Assistance Unsupported Software (AUR & Other)

When I use journalctl to check errors and warnings I see this message pop up over and over, like a thousand entries in just a day.

The offending code in the script is on line 51.

client.windowId.toString(16)

When I open the script with Kate, the output in the lower left flashes and gives me this warning.

I have used Pacman -Q to see if qmlls or qmlls6 were installed and got nothing.
I then used Pacman -S to see if they were available for install and got nothing again.

I then checked the Archlinux package search on their website, and neither qmlls or qmlls6 show up.

Thanks for any help.

Edit:

After doing a little more digging qmlls is part of QML 6.6 so I’m going to install qt6-declarative from the extra repository, since it appears that qmlls comes as part of the QT declarative package, and see if that helps. :grin:

Any other advice would be appreciated.

First post edited to swap out results of inxi -F with garuda-inxi.

After installing qt6-declarative and rebooting, the entire screen, except for the system tray, was greyed out. I removed qt6-declarative and rebooted, screen has color again.

installing qt6-declarative was not a good solution.

Can you try with an x11 session, unless you necessarily need Wayland?
I had not checked the details, sorry.
That script is not for wayland. See upstream:

And the last commit two years ago! :thinking:

Yeah, I did that, and now I just get new warnings about things being undefined. LOL

Apparently, no one wins at this game.

Is kwin-forceblur necessary for the plasma desktop on Garuda? I mean it’s part of the install package from the iso so assumed it was, but if it’s not something necessary for the system I don’t mind giving it the ol’e pacman -R.

For sure not necessary.
I don’t have access to the system at the moment, but I guess you can simply disable it in the system settings.

Awesome, and thank you.

It had me scratching my head for a minute after your reply. Like, if it’s not for wayland then why was it being called when I’m using the wayland session.

Fun thing is, I’ve had the blur effect disabled for a while now, and something was still trying to call that script.

I don’t think kwin scripts can be differentiated to run in x11 or Wayland. The folder is the same, and probably both kwin and kwin_wayland read there. But I’m not a developer, and much the less a KDE developer :wink:.
Why it runs, I don’t know. Maybe blur was disabled but forceblur (which I guess is something separate) was enabled?

I don’t even see an option to disable forceblur in the system settings.

I’m going to have to figure out where this thing is enabled, or what is calling it, and if what calls it has a config file I can turn it off in.

OMG!!!

I finally found the setting, and turned that crap off! How did I not find this before?

Check those files in how to use section in GitHub.
Maybe you can simply delete them.
Edit: ah, so my memory is not so bad. I did remember that, from the times when I liked to play with that stuff!
