LVGL also uses the vexDisplayCopyRect function:

Didn’t you say here that LVGL won’t interfere with the display unless actively showing something?

I don’t understand what the purpose of Brain.render() is, or how LVGL does the equivalent, which is probably where I will need help.

Btw, there is discussion to decouple LVGL from the PROS kernel, which will allow users to completely uninstall LVGL. This won’t be implemented anytime soon though.
