Problem with RM68090 TFT Screen

There are many libraries that support the "Mcufriend-style" Shields.
You never know which controller is mounted. (Ebay sellers are often ignorant or mendacious)

However MCUFRIEND_kbv supports more controllers than the other libraries. (Sometimes you have to enable the SUPPORT_xxx line in the library file) e.g. for HX8347 variants
