esp_lcd_st7701, V1.1.1, installed via component manager Seems to be missing a "Enable the Command2 BK0" in the RGB implementation of panel_st7701_mirror() which is present in the mipi implementation. replacing the part of the rgb function with the coresponding part of the mipi function fixed the issue. Don't know if this is the correct way to fix this.
