Hello, as stated in my (french) presentation, I was a happy Neon user and a fervent supporter of Plasma ! But that was before. I have just switched from 5.19.5 to 5.20.0. And now, disaster : Plasma doesn't work : the windows are no longer resizable, there is no more main bar (the top bar of the window as well as that of the menus), you can't move them using the [Alt] key, you can't move them using the main bar either, since it doesn't appear anymore. All the settings made prior to this "update" have disappeared, no more unplash background for example, but also all the long and complex configuration of the whole.
I'm using a dual screen that has been working perfectly for the last 3 years : 15" laptop screen + hdmi LG TV. Now I'm forced to start in Plasma Wayland to hope to (bad) achieve something, plasma or mobile plasma (which is rather tablet oriented?) don't work anymore. When I resize or move a window, I get blinking, blocking, sometimes ghost windows etc..

Thank you for taking the time to read me. See you soon I hope.

There was a problem with kwin_x11, but it was fixed a few days ago. Have you tried/managed to update it recently?
From the CLI, sudo pkcon refresh && sudo pkcon update

Thanks for answer, but all is upgraded and the problem still persist. What's your config ?

Operating System: KDE neon 5.20 (20.04 base).

So, basically, I have nvidia, you have Intel... the rest is pretty much the same.
my kwin_x11 --version says kwin 5.20.0. Yours?

5.20.0 like yours.

I have other issues, the most problematic is the copy/paste. Sorry to add more and more problems, but I find them along the time using Neon ...

I considere migrating toward a more stable distribution ... More basic maybe, and I I'm sorry about that, but I need something working !
