Now MS created a messy collection for 2 completely separate problems.
One deals with Cursor disappearing, while the one I filed is for the Text Select showing up in a black square. So much for clarity!
They are just creating more confusion.
Probably the new bug they added in 26080 may be caused by some of the changes they made trying to fix the cursor disappearing.
Still the 2 symptoms are completely different, and do not seem related at all for including in the same collection. 🤷♂️
