Description S 2019-07-08 19:06:10 UTC

Hi, I started experiencing this major bug in one of the recent Plasma/KDE/KF5 updates for openSUSE Tumbleweed (within the past week). 

Very frequently (within an hour or less) I notice that the Plama panel clock stops updating, and the App Menu and Calendar popups stop rendering (just the outline), and notification popups show black with a copy of the panel underneath. When I restart `plasmashell` it fixes it for a while, but later starts glitching again.

This is on a Thinkpad T530 laptop with integrated Intel graphics, running the X modesetting drivers (not xorg-intel driver). I tried switching the KWin compositor from X11 rendering to openGL, but it made no difference.

Hi, I tried switching to the official Intel driver for Xorg, but it is giving me the same trouble.

Same problem

Kubuntu 19.10
Plasma 5.16

I think it is not a Kwin problem, because restart Kwin doesn't help, but restart plasmashell fix this

Although I suspect that something KDE-related was janky, but for me it turned out to be related to the kernel version:
https://bugzilla.opensuse.org/show_bug.cgi?id=1140777
It started happening somewhere in the kernel 5.1.x lifecycle, and was resolved with kernel 5.2.

Comment 7 Andrei Ivnitskii 2019-11-10 14:35:39 UTC

I use kernel 5.3 and bug is still present. I think it is not kernel problem

Comment 8 Andrei Ivnitskii 2021-09-01 11:56:08 UTC

Any news? Bug is still present in Kubuntu 20.04
