As on Windows 11 & 24H2, the scrollbar arrows (thumbs) gets hidden after focusing on most applications but not on Win 11.
Seen now on all my applications D2007, Rio (32 & 64bit), but not using FMX or even Rio IDE.
As setting on Accessibility / Visual effects / Always show scrollbars ON.
This new scrollbar layout requires at least 2 lines on TListbox, otherwise thumbs as not clearly visible.
How to overcome this behavior?
