Wrong status of Icons on two different PC's

Hello all.

Since my update on OH3 I have the effect, that on my main used PC the homescreen is displayed wrong.
Most of the icons are shown as blue “active” which is not the case. They should be white “off”
“bild2” shows my my notebook which is ok. “bild1” shows my desktop pc which is wrong.
Booth PC have the same windows10, and the same browser, and version.
On my desktop PC all browsers show the wrong state. (Edge, Chrome, Firefox and InternetExplorer)
Under Android, iOS everything is fine.

So it seems to me, that exactly this PC (my desktop) has a problem, but with what?

Thanks for all your ideas.

Hello all,

does no-one from you has this effect, somehow?
