Which DE are you talking about? It sounds like KDE/Plasma but you didn't specify.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Apologies. It's KDE. I've udated the post.
Are you using Wayland with KDE? For me the taskbar freezes if I'm on Wayland and hover over some windows so it shows the preview.
If you're also using Wayland, try turning off window previews (right-click taskbar->configure->Show small window previews).
Also, as a workaround if this doesn't fix it for you, you can execute plasmashell --replace and it'll replace the existing frozen instances instead of starting new ones. If you use krunner (alt+space) it'll stay in your recent commands as well, so you can easily run it again when it freezes again.
I bound that command to meta+del because it was happening frequently enough to annoy the shit out of me. Bring on plasma6!
Can you confirm that it's only the taskbar that freezes? Do any other DE components (e.g. app launcher (shortcut meta + f2 by default)) work or do they freeze/not respond as well?
You could check various logs for errors:
- syslog (
/var/log/syslogordmesg) - unit files of Plasma components (
journalctl -xeu $UNITNAME; e.g.journalctl -xeu sddm.service)
Not on Debian, but I got this freezing with KDE Plasma Wayland with Nvidia driver. KDE Plasma Xorg works though.
My Intel iris laptop works fine with KDE Plasma Wayland.
OOT. My phone autocorrect Xorg to corgi 😂 but I cought it before sending.
On my Debian, Wayland crashed (after several hangs and glitches) and a reboot ended in a blinking cursor on black screen.
I literally didn't do anything except install it with everything on default and change some settings in the GUI.
Something is up with Debian KDE right now.
Did you install any non-standard graphics drivers? If your system has an nVidia GPU bumblebee, nouveau and the closed-sourced driver all can cause this issue.
No. Intel integrated graphics on a laptop.
And now on OpenSUSE, KDE works flawlessly, so it isn't a hardware issue either.
According to the debian wiki support is not fully guaranteed. Might just be that you ran into any of those issues:
Wayland support is still not finished yet though. Notably, there are issues with the compositor taking down other applications with it when it crashes, changing the global theme sometimes causes a session crash, "Activities" are unimplemented, there are various papercuts with drag-and-drop functionality, and session restoration only works with XWayland windows. A full and more regularly-updated list of Plasma Wayland issues can be found here: https://community.kde.org/Plasma/Wayland_Showstoppers
Then I find it weird that Debian Stable defaults to Wayland on KDE.
Unfortunately X11 isn't without issues as well. In my case Wayland runs smoother and is less error prone than X11.
