Fermion: 2.0" 320x240 IPS TFT LCD - smooth text display

Hi

Can someone please point me to documentation/examples of displaying changeing text on one location of the display without having to “refresh” or “clear” the screen each time you need to display another updated value in the same spot?

The Gitlab page for the GDI library has documentation that claims that there is a 1 hour video of alot of features - like implementing progress bars etc, but there is no link to an actual video? (https://github.com/DFRobot/DFRobot_GDL)
