Hi,
I’m getting a flood of these messages on my vm guest running fedora 44 and KDE Plasma 6.6
I’ve searched and have not been able to find any good matches for this.

the desktop seems to be working find and the message will log even if i’m not messing with windows but not as often.
I tried upgrading to Plasma 6.7 and had kwin_wayland go unresponsive and desktop hang so many times and wasn’t able to fix that so i downgraded. I wonder if this might have been the cause?
should i open a bug?
