Screenshot of the original document in Calc before and after hovering over the changes.

When comments and comment-like functions (eg: Change tracking) are hovered over with the mouse the background changes its color and after this scrolling and double clicking also changes the color. 
This happens when OpenGL is turned off on Windows.

Steps to reproduce:
1.	Create a new Calc file.
2.	Insert a comment or turn on change tracking and make some changes. 
3.	Hover over the comment or the changes so the pop-up window shows up.

Actual results: The background changed colors.


Expected results: The background shouldn’t change colors.
