I've read trough the topic.
So far I can see two problems that people have and that is confusing in solving the real problem of the topic-starter.
First problem is the cursor disappearing while starting to type. Solution to that is simple; unchecking the check box "Hide pointer while typing" in the Mouse Properties > Pointer options.
Second problem in this topic, and the one I also have problems with, is that the pointer isn't even appearing in some applications because the mouse is completely white with no shadow. This mostly noticeable in Office products. I see the problem happening in my local office and when I'm remoted in to work, which runs a different office. The mouse pointer is rendered locally. It appears, as mentioned, an AMD driver problem. This doesn't matter if it is a integrated or dedicated GPU.
Rolling back the video driver far enough back should theoretically help. The oldest downloadable driver on AMD website for Win11 is Adrenalin 22.4.1 Optional. If someone could test this, or even with an older driver found online (careful of your source!). I won't test it because this is my gaming machine, working once a week on it and my work doesn't involve a lot of typing. I need the latest driver for my game (Thanks Activision!).
Meanwhile I've found something stupid: If I keep the Mouse Properties open in the background the cursor is "more" visible in Office. It will sometimes fail and appear white but sometimes the cursor is drawn correctly in black. Second is when dual screen remote to work, the problem only occurs on one screen.
I'll take it for now.
