esp32 CYD: fillScreen "deletes" only 1 of 2 drawRoundRect areas

[Ozy3537]

Just receives a CYD (Cheap Yellow Display) and started with some first code for the new hardware and here I am ;)

My very simple code does

• clear screen = fillScreen(Grey)
• draw box no.1 = drawRoundRect
• draw box no.2 = drawRoundRect
• clear screen = fillScreen(Black)
  The screen should now be one black area,
  but the first roundrect stays visible (no change).
  The area around the first box gets also filled black.

Hardware:
esp32-2432S028 (v3?) CYD2USB (with 2 USB connectors, micro and type-c)

• esp32 wroom
• 2,8" TFT with ST7789 (afaik) - but I selected "#define ILI9341_2_DRIVER" in User_setup file
  no additional Hardware connected
