SUMMARY
When using plasma shell 5, fonts get corrupted in widgets which are scrollable
when scrolling up or down with keyboard or mouse, or when hovering with the

periodically, like sysmonitor
This issue affects (non exhaustive list):

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 5.12.9-arch1
(available in About System)
KDE Plasma Version: 5.21

ADDITIONAL INFORMATION
The panel text gets misrendered when the cursor gets idle for some time.
Interestingly, it does not occur in sysguard application
I've re-installed xorg, plasma, video drivers and the whole OS, nothing
changed.
I've tried the old xf86-input-evdev solution, as stated in
https://bugs.kde.org/show_bug.cgi?id=358472, nothing changed.
