Weird Google Chrome Issue

So I have both Windows 10 Pro and Windows 11 Pro running with multiple web browsers including Google Chrome.

For some odd reason a couple of versions ago the Browser Theme are broken in an obscure way.

See above the weird RED stripe across the top of the browser, under the tabs and above the URL field.

IF I disable the Google Chrome theme then it looks correct, I’ve tried a few random themes all with the same results.

Any ideas or is this an annoyance with the later version of Google Chrome that I have to live with or not use Themes.
