Why do Win10 Taskbar Icons sometimes "flash" for a second?

2

I don't mean "blinking" as in notifying the user, I mean that the whole taskbar seems to do a "reload" of sorts, where the icons completely vanish for like half a second (leaving a blank taskbar) and then return.

Is this a background system update triggering a restart of explorer.exe? I surely can't be the only one who has noticed/experienced this behavior.

If another task is using a lot of memory/CPU then explorer may have insufficient resources to redraw the taskbar in a timely fashion when requested to do so. – DavidPostill – 2018-05-13T08:19:59.380

Plausible, but I don't think it's a load problem. Everything stays snappy and everything else displays correctly. – T Nierath – 2018-05-13T08:44:59.057

Does the taskbar seem to freeze or crash right before it blinks & reloads? Maybe that's what it's doing, just crashing – Xen2050 – 2018-05-13T09:11:04.173

I don't think it's a crash. Notification area and such is not affected. Could be a redraw, but the thing is quite infrequent. I'm just curious really, it's not much of a nuisance. – T Nierath – 2018-05-13T09:19:13.830

I’ve seen the same behavior, and even wondered as to what Windows was doing. But it is so insignificant, I have never looked any further. – Appleoddity – 2018-05-13T13:10:48.387

I agree, at least I'm not the only person who has observed it. – T Nierath – 2018-05-13T14:11:45.610

If anything updates shell integration points (file associations etc.) then it may cause all shell windows to refresh, so that all files have the right icons, etc.

The desktop is just a shell view that's always "open", and that includes Taskbar etc. so that may be what's causing it to "blink"?
