Broken rendering in plasmashell

Widgets part of org.kde.plasma.systemmonitor seem to break rendering when added to plasmashell after my latest update.

Version of Plasma installed:
extra/plasma-desktop 5.12.2-1 (plasma) [installed]
    KDE Plasma Desktop
extra/plasma-framework 5.43.0-1 (kf5) [installed]
    Plasma library and runtime components based upon KF5 and Qt5


The only widget that appears to not break rendering is Disk Usage. Everything else will cause the widget appearance to turn completely black. This rendering bug persists after removing the widget, but if the widget is removed and you stop and start a new session, rendering is restored. It occurs irrelevant of the Desktop theme used for me. 

Attached is a screenshot.

Should this be relevant

OK, so I've located the source of this issue:

An upgraded library libepoxy 1.5.0-1 was the source of the rendering issues.

I downgraded to libepoxy-1.4.3-1 and the widgets now render properly.

I don't think this is a KDE bug.
