1316             [DS] Workaround for WindowBlinds:
1317             Some themes return a near black theme color using FILLCOLORHINT,
1318             this makes notebook pages have an ugly black background and makes
1319             text (usually black) unreadable. Retry again with FILLCOLOR.
1320
1321             This workaround potentially breaks appearance of some themes,
1322             but in practice it already fixes some themes.
