I have a new installation of Leap 42.1, and it seems to run Plasma 5
fairly well.
However I do tend to have this one consistent problem. When I open up
Chrome, after a few minutes, my desktop and screen locks up. It is not a
complete lock up, as I can still navigate on the web page I am looking
at, but I can’t go to other tabs, and cannot change focus of any
windows. Chrome remains in front and won’t go away, and I cannot move to
other virtual desktops or activities.
I can hit ctrl alt 1 and go to a terminal login, so that allows me to at
least see what processes are running. But even if I kill chrome and the
other desktop applications that are open, it doesn’t change the desktop
when I hit ctrl alt 7 and go back in. The only thing I can do to get out
of it is hit ctrl alt double backspace twice to kill X and then log back in.
It started doing this after I tried to install a program in wine that
didn’t work.
I have heard something about some processes trying to use old kde4 files
or qt4 files and that locking up the screen like this, but I really
don’t know where to begin troubleshooting this problem.
What do I need to post here to give more information? I can find logs
and post them or do whatever.

Take some readings on your system resource usage, particularly memory and memory buffer usage.
You might find my writeup on using the “Free” tool useful, but in your case run top (info is also available in top, see my article) https://en.opensuse.org/User:Tsu2/free_tool
Open a console and run top.
Grab a screenshot of top before you open your suspect app (Chrome in your case).
Take another screenshot when your system is experiencing problems.
Analyze memory buffer and cache usage changes using the article I wrote.
Consider running the command I give you in my write-up to clear your memory buffers and cache if you’re changing from one major work load to another.
What’s your graphic card and driver, plasma 5 has known bugs with intel cards and with noveau, the noveau bug is easy to get around just install nvidia’s propiatory drivers, the intel bug is hard to fix as it’s driver is build-in the kernel maybe use a different desktop, you can try lxqt (0.10 is great) or downgrade to kde4 or use wolfi’s repo and install both kde4 and plasma 5.
I don’t know why I didn’t see your post earlier. Thank you for the
suggestions. I am working on it now and will take the screen shots and
do the analysis again next time my machine locks up.
The problem seems to be intermittent - I just opened chrome with 17
separate tabs, and there was no issue with having it open. Yesterday I
had it open with only 4 tabs and my KDE locked up.

Yes, thank you for the suggestion. I am using a desktop with an MSI 970
gaming motherboard, and a separate MSI graphics card that uses a GF108
[GeForce GT 730] nVidia device. I have the nVidia driver installed from
suse nVidia repository.
I will try setting up Wolfi’s repo and using kde4 also and seeing if
that helps.
I’ve got the exact same problem but I don’t use Chrome. So I don’t think it’s specific Chrome. I use Firefox and have the same issue here described.
It’s a little bit frustrating. I more think (not build of facts!) it’s the System Tray.
I have a intel chipset laptop so I can’t change that.
If someone else has any idea what to do for debugging, please tell me.
I use Plasma 5 on Leap 42.1
It’s a intel based laptop.
If I kill the kwin process then most of the time the applications are responsive again. I’ve lost the bar of the application but I can go further.
If the screensaver kicks in and kde hangs this is not a solution. I need to use CTRL-ALT-Backspace.
Today it was 4 times. This is not workable and I really think of going to GNOME on my openSUSE.
