The screenshot above was taken when linking to STemWin 5.32
This is how it looks when using STemWin 5.40.
Within my project I replaced the library code under Middlewares/ST/STemWin and linked to the new object file STemWin540_CM4_OS_GCC_ot.a. My own DMA2D, LTDC, ili9341.c, GUIConf.c and LCDConf.c did not change.
Any idea what might be going on?
