Corrupted TouchGFX text

[dave2012]

I have a TouchGFX application where Flex Button text is sometimes being corrupted as are TextArea widgets (both with and without Wildcards). Images remain unaffected. The processor is a STM32U599, display type is RGB888 LTDC based and no external FLASH graphic storage is used.

The corruption cannot be cleared with a processor hard reset, only power cycling clears it.

From the attached image, the two 't' characters in the corrupted "Start" text are the same so it appears that a RAM based font bitmap cache is being corrupted. If so, any ideas where to find the name of this structure/buffer and is it managed exclusively by the TouchGFX library code?

Thanks

Is your issue after flash programming? I have same issues, but seems after power off - on all works. 

Yes affected is fonts seems all types, vector too, reported on other thread.
