I have a user on Win7 reporting that the background color of VirtualTreeViews is black under any theme in Win7. The app is compiled with Delphi 12 and the master branch of VT. Earlier versions compiled with Delphi 11 and older version of VT appear to work fine.
Is anyone aware of Vcl Styles issues in Win7?
Was there any changes in Delphi 12 or VirtualTreeView that may have had an impact on this?
