      I am re-creating an old stemWin project, written using IAR by programmers no longer with the company, to the Atollic TrueStudio.
      I used CubeMX to create a simple window based on the Discovery32F429I board, which is a single layer, 565-based setup. I then modified the project drivers to work for my larger, 2 layer board. The "Hello World" displays fine, but I have the following issues.

      1. I can't seem to get anything to display on layer 1. If I use GUI_SelectLayer(1) before writing, it does not display.
      2. The project includes bitmaps that display properly on the original system, but on my recreation display only the alpha portion of the bitmap (in white) and everything else black.

      I hope this is enough to recognize the issue. Any help would be appreciated.

      Thanks and Regards,
