And unlike the last one this is a bug, not a feature.
It’s related to the System Tray icons, whereby the issue causes some of them to move about in a weird manner, left and right. Dancing, basically. And as noted, funny as this error is, it does get annoying pretty quick.
The whole thing is caused by touch screen drivers, and it is affecting devices where a touch screen is available as Windows 10 tries to switch to the Tablet Mode.
Seeing as there is nothing from Microsoft in this regard, and this bug happens only occasionally, your only option is to try something yourself for a fix. Luckily, there are two ways to go about this, and both are worth a try if you encounter this problem.
First of all, you need to update your touchscreen drivers and see whether that fixes the problem. That is, of course, if your manufacturer has made new ones available for download.
If not, then the only workaround is to actually disable the touchscreen completely. This can be done via the Device Manager. And while this certainly is not the most convenient of routes, it seems to be the only way to get rid of these dancing icons.
Some users also found success by toggling the Tablet Mode options on and off, but this only seems to be a temporary resolution.
Hopefully, Microsoft is here with a permanent one soon.
