Pygame lagging with texts

Question

I was creating my Cuphead inspired game, a fan game and I was creating the warning text and it is lagging a lot like 0-2 fps if anyone can help me I would be very grateful, I don't know if programming on the cell phone interferes with anything or it's the same thing but anyway if you can help me thank you

My code:

import pygame
import sys
pygame.init()

resolutions = ['1152, 648', '1280, 720', '1365, 768', '1600, 900', '1920, 1080']

screen_max = ((1920, 1080))
screen = pygame.display.set_mode((screen_max), pygame.FULLSCREEN | pygame.SCALED)

game_fontT = int(screen_max[0]/30)
game_font = pygame.font.Font('Fonts/AlegreyaSansSC-Bold.ttf', int(game_fontT))

FPS = 60
click = False

linguas = ['espanhol', 'ingles', 'portugues']

lingua = linguas[2]

Warn_Screen = True

def show_fps():
    fr = str(int(clock.get_fps()))
    frt = game_font.render(str(fr), 1, pygame.Color("coral"))
    return frt

def text(text, posx, posy, R, G, B):
    posx = int(posx)
    posy = int(posy)
    R = int(R)
    G = int(G)
    B = int(B)
    score_surface = game_font.render(f'{text}', True, (R, G, B))
    score_rect = score_surface.get_rect(center = (posx, posy))
    rgb_surface1 = game_font.render(f'{text}', True, (0, 255, 0))
    rgb_rect1 = score_surface.get_rect(center = (posx-1, posy-1))
    rgb_surface2 = game_font.render(f'{text}', True, (255, 0, 0))
    rgb_rect2 = score_surface.get_rect(center = (posx+1, posy+1))
    screen.blit(rgb_surface1, rgb_rect1)
    screen.blit(rgb_surface2, rgb_rect2)
    screen.blit(score_surface, score_rect)

clock = pygame.time.Clock()
while True:
    screen.fill([255, 207, 17])
    ftr = show_fps()

The text is static, so instead of rendering the text every frame, draw the text on a surface before the application loop and blit that surface every frame.

Write a function that draws a text with multiple lines on a transparent pygame.Surface.A transparent surface can be created with the flag SRCAPHA:

def renderText(font, color, textList):
    fontHeihgt = font.get_height()
    textSurfaceList = [font.render(t, True, color) for t in textList]
    width = max([s.get_width() for s in textSurfaceList])
    height = len(textSurfaceList) * fontHeihgt
    textSurface = pygame.Surface((width, height), pygame.SRCALPHA)
    [textSurface.blit(s, (0, fontHeihgt*i)) for i, s in enumerate(textSurfaceList)]
    return textSurface

See also Rendering text with multiple lines in pygame.

Use this function and render the text before the application loop and blit the text inside the loop.

Minimal example:

import pygame

pygame.init()
window = pygame.display.set_mode((400, 400))
clock = pygame.time.Clock()

def renderText(font, color, textList):
    fontHeihgt = font.get_height()
    textSurfaceList = [font.render(t, True, color) for t in textList]
    width = max([s.get_width() for s in textSurfaceList])
    height = len(textSurfaceList) * fontHeihgt
    textSurface = pygame.Surface((width, height), pygame.SRCALPHA)
    [textSurface.blit(s, (0, fontHeihgt*i)) for i, s in enumerate(textSurfaceList)]
    return textSurface

font = pygame.font.SysFont(None, 50)
text = renderText(font, (255, 255, 0), ["This is a", "multi-line text.", ";-)"])

run = True
while run:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False 

    window_center = window.get_rect().center
    window.fill(0)
    window.blit(text, text.get_rect(center = window_center))
    pygame.display.flip()
    clock.tick(60)

pygame.quit()
exit()
