I've been seeing strange things on my panel for about a week or two.  They are triangles or lines extending horizontally from a region of some color, narrowing to a point.  They last generally for up to about 30 seconds.  Attached is a picture of such an artifact (PanelArtifact.jpg), taken with my cell phone.  Note the black stripe just above "System Information".  Has anyone seen anything like this

System: Fedora-32 all updates installed

Processor:  4 x Intel i5 4460 CPU at 3.2 GHz

Memory:  15.5 GiB RAM

Video System: Xorg (not Wayland)

Graphics: Mesa DRI Intel HD Graphics 4600

KDE Plasma: 5.20.5

KDE Framework: 5.78.0

Could it be a hardware issue?  It has an intermittent quality that looks like hardware trouble; but then why would the artifacts happen only in the panel?
