plasma-systemmonitor-20220824-205131.kcrash

The issue occurs also in plasma-systemmonitor, but only for the following
sensor faces:
1) org.kde.ksysguard.linechart
2) org.kde.ksysguard.processtable
3) org.kde.ksysguard.applicationstable
Sensor faces listed below work fine:
1) org.kde.ksysguard.piechart
2) org.kde.ksysguard.textonly
3) org.kde.ksysguard.horizontalbars
4) org.kde.ksysguard.facegrid
5) org.kde.ksysguard.barchart

I've created a minimal test case in QML using SensorDataModel from
org.kde.ksysguard.sensors and LineChart from org.kde.quickcharts trying to
narrow down the issue but alas everything works without an issue.

I've modified org.kde.ksysguard.linechart to display a static chart, using an
example at
https://api.kde.org/frameworks/kquickcharts/html/classLineChart.html
but it fails in plasma-systemmonitor as well. It crashes eventually (.kcrash
log attached). 

I'm not sure what can influence the flickering and not really know Kirigami or
KQuickCharts.

Could it be that they use extensions unsupported by my gpu driver like e.g.
ARB_buffer_storage (my glxinfo attached)? Such bug has been solved at
https://bugs.winehq.org/show_bug.cgi?id=52663

Any ideas on what could be checked?
