set_key_image() erases touchscreen content if it was not called before set_touchscreen_image()

[devleaks]

Describe the bug
If you call set_touchscreen_image() the image appears on the LCD display.
If you call set_key_image() after, it erases the content of the LCD (the first call).

To Reproduce
In the example_plus.py file, simply invert the drawing on LCD loop and drawing on keys, draw on LCD first, then on keys.
The LCD content will be erase.

If you call set_key_image() first, then set_touchscreen_image(), everything works as expected, consecutive calls to set_key_image() do not erase the LCD.

LCD is erased just by the first call to set_key_image() if set_touchscreen_image() was called before.

Thanks for the report. I'll need to get physical access to a device to debug, I think.

Please let me know if I can test something, I bought a device to test...
I suspect there is a flag or a combination of flags, a bit in the header that provoque a clear screen.
