Kwin_x11 Crashes when selecting Dark mode

Hi all,

I thought I’d give UbuntuDDE a spin as I very much like the look of the Deepin Desktop… particularly dark mode. I’m booting the 22.04 ISO using VMware 16.2.3.

Even before installation, using the LiveCD environment as soon as I switch to Dark Mode a few seconds later Kwin crashes repeatedly. Eventually the dock vanishes, the errors disappear and I’m left with an empty desktop (background still there). Only a reboot restores order.

This anomaly only occurs when I select Dark Mode.

Hope some light (or dark) can be shed on this.

Thanks in advance,
TC
