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

It sort of looks like it would be coming from whatever icon is to the left of the clipboard icon. When this stops happening, is there another icon there?

There is another icon there, the kalarm icon. But I don't think this has anything to do with the issue. Artifacts appear all over the panel: they appear to be extended from any icon on the panel and seem to have something to do with the cursor. I had thought it had something to so with overloading the system; I frequently run Firefox with many windows and tabs; but the artifacts appear whether or not Firefox is running.

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?

You can move the panel to the top and see if the artifacts follow.

Continuing: It does look like a hardware issue that affects only KDE Plasma. I see these things intermittently and only in plasma, i.e. the desktop, the panel, and the start menu. They have become more pronounced, often flickering between this (normal)
and this (black panel, etc)
I'm planning to replace the CPU intel i5-4460 with an intel i7-4790. Let's see it it makes a difference.
