<![CDATA[cfg.clear_display=false has no effect on PaperS3?]]>I might post this as a bug: cfg.clear_display = false seems to have no effect on the PaperS3. It would be useful to have it work because the device could be woken up without having to rewrite the whole screen. Perhaps this is a hardware limitation?

include <epdiy.h>
#include <M5Unified.h>

void setup() {
  auto cfg = M5.config();
  // This seems to have no effect:
  cfg.clear_display = false; 
  M5.begin(cfg);
}

May ways to workaround for the time being.

this issue has been fixed in recent M5Unified and M5GFX libraries - see here. Make sure you are using the latest versions of these two libraries.

BTW: I am using this feature in my non flickering RTC clock example - see here.

Thanks
Felix
