Did you try all 3 of the pointer color/size options? The mouse pointer, no matter what size or color, should only overlay (block) text when the text is "selectable". So even if you made it white, it would overlay with a white pointer. I may not be real clear on what your issue is. Sorry.
I'm not real sure what '"
RH toolbar's "speakers / headphone" and "new notification"' means? What is RH? Is this Realtek High def?
In the customize icons section, choose "show notifications and icons". On your taskbar, in notification area, is there a small white triangle? If you hover over it, it will say "show hidden icons". If you click on it, it will show any icons that are hidden. If you want these to always show, set them to "show notifications and icons".
You may need to reset you notification area icon cache. It can sometimes get a bit quirky! Attached is a batch file you can download and run. It will clear the notification area icon cache, both previous and current, and restart Explorer, at which time the icon cache will be rebuilt. It was written by Shawn Brink, so it's OK! Here's what it looks like, but download and run the .bat file.

Get back with results, pls. Thanks, Dick.
P.S. F4 Phantom was great back in 'Nam days, but it belched way too much smoke!
