Screen artifacts since upgrading to KDE 5.23

[Taliesin]

I use the term screen artifacts, as I don't know how else to describe it.

Since upgrading to 5.23 I get a persistent "image" from an application on all desktops.

This can be,

• 1, an image of the entire application or,
• 2. an image of a drop down menu.

This persists after the application has been closed.

It doesn't happen often, but often enough to be very annoying.

It occurs with KDE / Plasma apps i.e. Dolphin or non KDE / Plasma apps i.e. Firefox.

It can be cleared by logging out of a session then back in again.

Any one else experience this at all?

Any ideas suggestions would be welcome.

Happy to provide additional information required.

Cheers.

My windows and widgets are flickering

The road on Plasma seems very bumpy at the moment
