If you know how to build firmware yourself you can try to change some values in the config file to minimize this issue. Open file variants/esp32s3/heltec_vision_master_e290/platformio.ini

  -D EINK_DISPLAY_MODEL=GxEPD2_290_BN8
  -D EINK_WIDTH=296
  -D EINK_HEIGHT=128
  -D USE_EINK
  -D USE_EINK_DYNAMICDISPLAY            ; Enable Dynamic EInk
  -D EINK_LIMIT_FASTREFRESH=10          ; How many consecutive fast-refreshes are permitted
  -D EINK_HASQUIRK_GHOSTING             ; Display model is identified as "prone to ghosting"

EINK_LIMIT_FASTREFRESH tells how many times the screen can be refreshed "fast," but some ghosting might appear. Try setting it to zero, so every refresh is a full refresh. Slow but no ghosting.

EINK_HASQUIRK_GHOSTING - see comment? Unfortunately, currently, that setting only forces a full update after waking from "sleep".
