I installed Debian 12 on a laptop. I found that when the mouse was moved up to the top menu bar it disappeared. If I managed to click on the menu the mouse was invisible over the menu too. Also I noticed the letter A from activities was missing.
You will forgive me I hope for installing OpenSUSE 15.5, but I still see some problems with fonts although the mouse is always visible.

What can I do? I would install Debian 11 or 10 if I thought it would improve the situation but I am not sure where the problem lies.
