Are you using NVIDIA binary OpenGL drivers? (In reply to Christoph Feck from comment #1) > Are you using NVIDIA binary OpenGL drivers? No. I do have an Nvida card but it's blacklisted (I'm using it for VFIO in a KVM). Fedora is running on the mobo's IGP. I'm having the same issue, although freezes don't take any longer than a minute. Noticed that when it happens plasmashell is using 100% CPU. Restarting plasmashell unfreezes things immediately. I'm on KDE Neon 5.14, Plasma 5.14.4, nvidia-driver-390 Didn't have this issue when I was using Kubuntu 18.04 on the same hardware, also with the proprietary nvidia driver.

I haven't had the problem recently (i.e. more than a month). I'm now on: kernel 4.19.10-300.fc29.x86_64 Plasma 5.14.4 I'm also not automounting my NFS NAS (via systemd). It's unclear which if any of these things has affected the issue. I believe this is a dupe of https://bugs.kde.org/show_bug.cgi?id=401272 Sorry, commented on the wrong issue, got tabs mixed up, please disregard my prior comment :( I may have the same or a similar issue (debian-testing, plasma 5.14.5, Intel graphics, nvidia blacklisted) which appeared at the same time as an update about a month ago which also broke kwin_x11. The panel display only freezes at random points while e.g. I can still click on its components and get a reaction. However, of course, state changes are not reflected in the panel any longer as the display remains frozen. I have never observed it unfreeze, even after hours.
Kill/restart will get things back to normal.
I can attach gdb and get a stack trace - maybe it helps:

stack trace of plasmashell (panel with display frozen)
If it reacts to click, it's not frozen, so the stracktrace won't tell us much. Does everyone experiencing this have NVIDIA hardware? Is anyone able to reproduce it with Plasma 5.21?
