Screenshot showing the two problematic widgets, as well as the System Load Viewer widget that does work for me, displaying the graph as intended.

SUMMARY
My CPU Load Monitor and Memory Status widgets have stopped displaying the graph that displays the system runtime info.

STEPS TO REPRODUCE
1. Unlock widgets.
2. Add a CPU Load Monitor widget or Memory Status widget to the desktop, or to a panel.

OBSERVED RESULT
The labels in the widgets are displayed correctly, as are the text information, but there is only empty space where the graphs should be.

EXPECTED RESULT
The graphs should be shown in the widgets.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Arch Linux
KDE Plasma Version: 5.17.4
KDE Frameworks Version: 5.65.0
Qt Version: 5.13.2
Graphics Driver: Nvidia 440.44

ADDITIONAL INFORMATION
In the past, I have been able to trigger this issue by switching to a virtual console, and back. However, the issue would never persist through reboots.

The recent event that I believe may have led to this being persistently nonfunctional is that, after a driver crash of sorts, my tray icons became low resolution with broken alpha, and a warning was displayed in my tray about having switched to software rendering. A reboot fixed my tray icons and made the warning go away, but my RAM and CPU widgets still don't display their graphs anymore.

all system monitor widgets have been recently rewritten from scratch
