I've encoutered the following bug.
When handling a VideoResize event, I change the display size using pygame.display.set_mode. After that, it seems (most of the time) subsequent video resize events are not returned by pygame.event.get
Play with window see see how sometimes events are generated, sometimes not. It seems that when only stretching the window horizontally or vertically, all events are processed, but when stretching horizontally and vertically at the same time (e.g. when you drag a corner of the window) events are not processed.
Note that if the call to display.set_mode is commented out, all resize events are returned by event.get (but the display surface is not resized, so the application is functionally broken).
System: Xubutu 18.04
Python version: 3.6.8
Pygame version: 1.9.6 (via pip3)
Example code:
import pygame
import time
import random
pygame.init()
surface = pygame.display.set_mode((600,400), pygame.RESIZABLE)
quit = False
while (not quit):
for event in pygame.event.get():
#quit event
if event.type == pygame.QUIT:
quit = True
#escape key (also quit)
elif event.type == pygame.KEYDOWN:
if event.key == pygame.K_ESCAPE:
quit = True
# resize event
elif event.type == pygame.VIDEORESIZE:
print("resize event",event)
# LOOK: here is the problem: calling dispay.set_mode, seems to block future resize events!
surface = pygame.display.set_mode((event.w,event.h), pygame.RESIZABLE)
# fill with random color to visualize the problem
col = (random.randint(0,255),random.randint(0,255),random.randint(0,255))
surface.fill(col, (0,0,event.w,event.h))
pygame.display.update()
#endif
#endfor
#endwhile
