Mouse cursor disappears with some background colors
lazarus / 31-LCL

I'm writing an application that uses different mouse cursors (some
predefined, some custom) depending on the contexts, with different
background colors, inside a scrollbox.

I noticed that some combinations of cursors and background colors
cause the cursor to disappear. Is it possible to ensure that the
cursor is always visible, regardless of the background color?

I attach a trivial example to reproduce the problem, which occurs in
Windows 10 64 bit with Lazarus 3.8.

Thanks in advance.
